VoIP has been ushered onto the iPhone in quite a few incarnations, but we'd wager than none of 'em are as useful as iCall. Said application is currently in beta form, though a release isn't quite ready for the public at large. Put simply, it enables iPhones to switch from GSM to WiFi (when WiFi is nearby, of course) on-the-fly in order to save cell minutes and bypass the hassle of manually changing over. Interested? We thought you'd be -- hop on past the break to see a demonstrative video of the app in action, and keep a close eye on the read link for a sure-to-surface-soon download.

Why should smartphone and 3 Skypephone users have all the fun? Skype has finally released a client written for mobile Java, enabling the ubiquitous VoIP pipe to be used on a wide, wide variety of phones (Skype says they've tested it on about 50, but it's likely to work on far more than that). Though it's naturally scaled down a bit to fit in its tiny target footprint, the client still manages to pack in support for Skype-to-Skype and SkypeOut calls, chat, group chat, and your buddy list -- pretty much everything you need to make it functional. If you're going to have a go at it, just make sure you're on a sufficiently generous data plan, k?

[Thanks to everyone who sent this in]

Update: Turns out the data plan doesn't have to be that generous. Straight from Skype: "Tom has 20 Skype contacts and signs in twice a day for a total of 90 minutes. He IMs for about 25 minutes each day and makes 20 minutes of Skype calls. Tom would use just under 1 MB of data in one month." Thanks, everyone!

Sure, the iPhone is cool looking, works out a lot, and is really good at math... but it can't do VoIP, can it? Well, yes it can -- and you can, thanks to a company called Fring and a piece of ingenious software (for jailbreakers only). Using the native app, it's now possible to place and receive calls via your WiFi connection, thus making AT&T CEOs cry like little babies. Besides doing Skype and the like, the app also lets you connect for chats via MSN Messenger, ICQ, GTalk, SIP, Twitter, AIM, and Yahoo!, which should make this an attractive package even if you don't want to harness the raw power of IP telephony. You can get the application for free by loading up Installer with the company's repo. Check the video after the break to see the magic happen.

The next episode of the ubiquitous Pearl is now available in T-Mobile stores across the land, bringing the spec sheet in line with the features Sprint, Verizon, and AT&T customers have been enjoying for a little while now -- a 2 megapixel camera, external microSD slot, and 3.5mm headphone jack, just to name a few. Unlike the 8130 for CDMA networks, the 8120 that T-Mobile and AT&T share adds a 802.11b/g radio, but the T-Mobile version packs yet a couple more tricks up its sleeve -- you know, the ones you'd probably expect of any modern T-Mobile phone with WiFi, namely support for myFaves and HotSpot@Home. That last bit about the WiFi calling is where it gets really interesting. Put simply, the experience we had setting up, using, and making calls with the new Pearl linked up to our router was the best we've had so far with any HotSpot@Home device; it definitely seems like T-Mobile and RIM are learning a thing or two about how to make this a truly seamless and painless process. A "UMA" indicator on the display lets you know that calls are being routed over the service, but if you're not paying attention to it, you might never know it's happening -- it's just that good. Grab it starting today for a shade under $150 on contract, or if you'd prefer to keep your money firmly in your pocket, you can still live vicariously through our gallery here!

Fresh off an announcement for an April 14th release, the latest rendition of the Pearl for T-Mobile -- the WiFi-enabled 8120 -- is strutting its stuff in its natural (somewhat natural, anyway) habitat. Casual observers would have an awfully tricky time telling this apart from the Pearl 8100 of yore, but the trained eye will notice a "WiFi" logo chilling on the display and a mildly revised keypad layout here. Probably just a matter of time before T-Mobile has these bad boys in every color of the rainbow, we imagine.

We'd have never guessed that the year and a half-old Nokia 6300 would be the target of an update, so color us surprised. The 6300i is a pretty mild refresh of the 6300, offering the same physical appearance, microSD slot, 2 megapixel camera, and Series 40 underpinnings, but the "i" model's got one big ace up its sleeve: WiFi. Nokia's using the opportunity to push the promise of cheap VoIP calling hard -- a nice feature, especially considering the phone's reasonable price of €175 (about $272) -- along with fast internet access. 'Course, without 3G on board, don't stray too far from those hotspots. It looks like we can expect the 6300i (at least in places where the missing 850MHz band isn't needed) some time in the second quarter.

It's not every day that we hear about a Windows Mobile 6.1 Standard device that lacks any cellular hardware whatsoever, so when we do, it's sort of like winning the lottery except way less exciting and profitable. Enter the first volley of devices to support Motorola's new Total Enterprise Access & Mobility initiative -- TEAM, conveniently -- which represent just the very front end of a whole infrastructure solution for business campuses looking to replace their desk phones with something just a little more mobile and modern. Eventually, TEAM will support true VoIP-cellular handoff, but in its initial form, it'll be WiFi only, making these first handsets very unique indeed. We don't have the complete picture on specs here, but they'll support push-to-talk, text messaging, and as we mentioned, they'll be loaded with the very latest and greatest that Windows Mobile have to offer when they launch later this year.

Ridiculous quantities of 3G handsets weren't the only things showed off at this year's Mobile World Congress -- oh no, NetIndex, Kaga Electronics and Runcom shook up the norm a bit with their WiMAX-enabled portable VoIP phone. Reportedly, the trio joined forces to develop a VoIP handset that utilized a 802.16e module, and aside from "realizing all-IP voice communication," it also sports a web browser and integrated WiFi for times when a plain ole hotspot will do. Sadly, we've no idea where this thing will go after it leaves Barcelona (nor what it looks like), but here's to hoping it makes a commercial debut -- and can decide on a single logo -- in the not-too-distant future.

We've learned that T-Mobile is prepping to roll out trials of the next episode in its HotSpot @Home service, entitled "Talk Forever." What's the diff? Unlike plain vanilla HotSpot @Home, Talk Forever will require custom WiFi routers manufactured specifically for the service; that kinda sucks, we suppose, but in return, the new routers can feed traditional landline phones of your choice by supporting up to two SIM cards internally. Trials will be rolling out in Seattle (T-Mob's home town) and Dallas in February, and it seems that the carrier will be offering the service in both landline / mobile combo and landline-only configurations. Now, here's where it gets a little weird: we just Googled "HotSpot @Home Talk Forever" and stumbled upon www.tiltyourworld.com, a site that appears to be some sort of Talk Forever training site for T-Mobile folk. But guess what? The exact same site was used for training AT&T folk on the Tilt a few months back! What gives? Anyway, follow the break for a quick breakdown on the goods.

Right on schedule, you're looking at the just announced co-branded Skype phone: the 3 Skypephone. Sure, mobile Skype clients are already in worldwide use. This, however, marks the first time a carrier has fully embraced Skype which traditionally has been seen as a threat to carrier tariff schemes. Under 3's plan, Skype VoIP calls and IMs are free to any other Skype user just as long as you're under contract or top up your pay as your go account with at least £10 (about $21) each month. The £49 (about $101) 3G phone with 2 megapixel camera and microSD slot will be available in the UK on Friday; Australia, Austria, Denmark, Hong Kong, Italy, Ireland, Macau and Sweden sometime later in the year. Wanna see it in a video? Sure you do, locked-and-loaded right after the break.

We aren't etching this in stone just yet, but we've seen numerous reports claiming that the recent partnership between 3 and Skype will soon lead to an actual piece of hardware. Reportedly, the 3Skypephone will be available on October 29th "for a pre-launch," and will be officially official on November 2nd. Specs wise, it should feature free calls to other Skype users / 3Skypephone owners, a two-megapixel camera, video capturing and an MP3 player. Interested consumers can supposedly choose from three different colors, and it should be available on the "£12 ($25) Mix and Match 100 tariff which offers 100 minutes or texts or any mix of the two." Ah well, at least we've but a few days left to find out for sure, eh?

Handover technologies are nothing new, but Agito Networks is hoping to offer up scalable systems that can "hand voice calls over quickly and accurately between company WiFi and cellular networks." More specifically, the startup system utilizes RF to tell when an individual is approaching "predefined points at the limit of the company's WiFi coverage," after which a mobile-based client cooperates with a RoamAnywhere router (which integrates with the company's IP PBXs) in order to hand the call over. Reportedly, the actual transfer "takes less than one second," and administrators can even set up RoutePoints and instruct calls to be sent directly to voicemail when users are off duty. Granted, it seems Agito is aiming its products at medium-to-large businesses looking to save on cellphone bills, and if all goes well, models ranging from $9,995 to $24,995 should hit the US by the year's end.

Details are pretty light on this one, but Reuters is now reporting that Skype and UK cellphone operator 3 are currently working on a new handset that promises to "make Internet calls mobile." According to Reuters, the phone is expected to "work in the normal way," but also include an option to let users bypass all those hefty cellphone charges and contact other Skype users directly in order to save a few bucks. We assume that means Skype will operate over 3G data, although that's yet to be confirmed by either party. We should know more soon enough, however, as the handset is apparently on track to be released before the end of the year.

Are you ready to have your brain go flying out of the back of your skull? If you said yes, be prepared to lose your mind... repeatedly. One of the Holy Grails / Seven Wonders of the iPhone World has been loosed upon the Earth today, namely: VoIP. According to a company called Truphone, they have unlocked the secret of IP telephony on the iPhone, and demonstrated said ability today at DEMOfall 07 in San Diego. Executing commands via the Terminal (i.e., on a phone which had been Jailbreak-ed), Truphone CEO James Tagg was able to call another mobile phone using only an IP connection -- all without breaking the SIM lock. According to the company, the software is still in beta, but they soon plan to have a version which will simplify activation, and allow seamless switching between WiFi and SIM use. Clearly, an exciting development for iPhone users, but a cringe-inducing situation for AT&T. Check the video after the break to see it all in action.

For those not courageous enough to give the SoonR Talk workaround a go, fret not, as Skype has finally arrived (for realz) on the iPhone. SHAPE Services has introduced IM+ for Skype for iPhone, which is simply a Safari web application that enables one to "access the Skype ecosystem from the mobile environment." Reportedly, the app was "designed especially for the iPhone's touchscreen," and best of all, it's being offered up gratis "for a limited time." So go on, point your iPhone to SkypeforiPhone.com and get to to yappin', ya heard?
