The hot word on the street is that Palm has all but confirmed the existence of two new phone models by ramping up a "launch developer" program for new applications. The devices, dubbed Zeppelin (a name we've heard quite a bit of) and Skywriter (which is new to us) could be slated for a Q3 release, as Palm is asking devs to turn in their applications by May 30th. Rumor has it that at least one of the units is a "Centro-like" Windows Mobile phone -- if that date is close to correct, it could very well be the "Wanda" that we saw back in January. The Zeppelin, on the other hand, is likely the WiFi equipped Treo 800w we've been hearing about for what seems like a million years. A mockup of a device (above) was included in the email, though we're pretty sure not even Palm could create a phone that ugly.

With the comforting knowledge that HTC's lovely new devices are inbound for Sprint, we admit, we're having an awful time working up excitement over the 800w at this point -- but we've got to give all these things a fair shake on the open market before we figure out who's king of the Windows Mobile hill this year. WMExperts claims that Sprint is now targeting July 22 for the grand entrance of Palm's latest Treo, a date that would still jibe with the timeline we've already seen in the wild. The potential launch date also brought with it a handful of new tidbits: Windows Mobile 6.1, integrated GPS, an illuminated keyboard that falls between the Centro's and the 700 series size wise, and it's apparently "very fast." It also seems that Sprint's version will likely be coming in Charcoal Black, a color that would fit in nicely with the carrier's trend of launching dark-ish smartphones. If the Curve is any indication, it's a color that'll suit the device well.

British carrier O2 has added the previously Vodafone-exclusive Treo 500 to its roster of business class smartphones. O2 is offering Palm's latest Windows Mobile handset for free with certain data and voice plans, which is probably the only way the company could get anyone to take these underwhelming hunks of plastic off their hands.

Word on the street (or via super-secret emails) is that Palm is about to begin beta testing on a fancy new device. Apparently, an email went out to select individuals calling for Sprint customers who will use Bluetooth devices and have access to WiFi. The email further requests that potential testers be "seasoned business professionals" who "commute and spend a ton of time working on email and on the phone." From the sounds of things, the company is gearing up to road test its heavily rumored, WiFi-equipped Treo 800w, a Windows Mobile device likely sporting 6.1. If you don't know what we're talking about, it's that mildly dated looking device from Gates' CES keynote that we've also seen in leaks recently. Nice going on the new spec and inclusion of WiFi (at long last) -- now how about some new form factors?

It's not often that a single handset unites all four US national carriers (assuming the T-Mobile thing ends up going down), so we have to give Palm some credit here -- it's an honorable feat. And with the Centro being a surprise break-out success for Palm (a much needed one, may we add), there's no reason to think they won't be able to push a few units on Verizon, too. The first color to launch on Big Red (but probably not the last) will be the very same blue that we've previously seen launch in Mexico. How does everyone feel about it? Check out the gallery for the full host of press imagery!

Feeling pressure from its smaller, sexier, newer cousin -- and every other smartphone, for that matter -- it looks like the Palm Treo 755p has taken its final bow on Sprint. With the Centro stealing the overwhelming majority of the Garnet limelight as of late, it seems there may be little business justification for another Palm OS device on Sprint's network; ironically, Verizon's version just launched four months ago, so we wouldn't sound the final death knell for the devicejust yet. For what it's worth, the classic Treo form factor lives on Sprint thanks to the 700wx -- another Palm device that's getting just a little long in the tooth (like 2006 long in the tooth). We'll admit, we'll probably shed a quick tear or two when the old-guard Treo line finally takes a permanent vacation in favor of newer, more modern looking designs, but we're not really mustering much eye moisture for the 755p here.

Update: We've gotten word straight from the horse's mouth that the 755p isn't discontinued -- it's merely out of stock, hence the disappearance from Sprint's site. They're "addressing [the] temporary outage of inventory," though, so if you've got a hankering for the larger Garnet piece in Sprint's lineup, hang tight!

Seems a little bizarre that AT&T would choose to launch white and lime over this more conservative choice -- but they did, and our Mexican friends get to reap the benefits. The blue variant of the GSM Centro is available via Telcel and Movistar -- exclusivity's apparently not an issue here -- and offers specs that are otherwise unchanged from its international cousins. Eh, on second thought, we think we like the white better anyway.

Palm's miniscule and wallet-friendly Centro has managed to reach one million units sold since its launch last September. It got its legs working as Sprint and AT&T's gateway smartphone at that fantastic $99 pricepoint, and now it's making a bid for world domination in major markets in Europe and Asia. The one million sales have it nipping at the heels of recent superstar smartphones, the two million plus HTC Touch and the four million plus iPhone, not bad company in the least.

We've gotten the inside track on a few dates on Verizon's radar for the next few months, and it looks like the boys and girls in red are prepping an interesting mix of exclusive and Sprint catch-ups to keep customers fat and happy. As handsets go, the Motorola Q9c is planned for April along with the TouchFLO-powered XV6900, LG enV2, and the CDMA rendition of the BlackBerry Curve (so much for exclusivity clauses on this one, it seems), while the Samsung Glyde is currently slated for late April or early May. Centro fans will be happy to hear that the diminutive Garnet phone will finally hit Verizon following Sprint and AT&T launches in the tail end of May or the beginning of June, followed shortly by the Nokia 6205, which apparently isn't either the 2505 or 7205 unless one of those flips have been renumbered.

As technology goes, Verizon looks to launch EV-DO Rev. A-based push-to-talk services -- Sprint folks will know this as Qualcomm's QChat -- toward the end of May. We've also caught wind of something called "Verizon Hub," which we're told will go head-to-head with T-Mobile's HotSpot@Home service. It's not known whether this'll be a WiFi setup (a la HotSpot@Home) or adopt Sprint's CDMA femtocell strategy, but seeing how Verizon and Sprint seem to be endlessly engaged in a game of cat and mouse, we wouldn't be surprised to see 'em go with femtocells. We don't have a date on Hub just yet, but it's targeting the second half of the year at the earliest.

Update: Commenters are noting that Verizon's do-all FiOS phone bares the "Verizon Hub" name, though it doesn't go head-to-head with HotSpot@Home -- and the Hub we're referring to is showing up on Verizon Wireless roadmaps. Weird. We'll keep a close eye on this one.

At this point the Treo 800w has been outed by Bill Gates himself, so while the suspense factor is pretty low, it's nice to know that it'll finally be getting here in July. That's the word according to this purloined Sprint roadmap, which also indicates the newest Treo will have GPS and EV-DO rev. A -- but still run WinMo 6.0, which is pretty sad, especially if that revised version of 6.1 launches at CTIA next week as expected. Oh well, at least it's a new Treo -- let's just hope they can shake some more ugly off this thing before it hits the street.

Great news: the more business-friendly alternative to the white / green wild child is filtering into an AT&T store near you. Turns out that pre-production units were seen sporting both metallic and solid black paint jobs, but the final units are solid -- probably the best option, considering that this one will likely see time on a corporate boardroom table or two. Can't have those sparklies reflecting in the fluorescent lights, now can we?

Well golly, no wonder Palm's gone on the attack against RIM. Corporate users have historically been the bread and butter of Palm's Treo line of smartphones, and with BlackBerrys of all shapes and sizes continuing to eat every other manufacturers' lunch in that profitable arena, it only makes sense that the company would be feeling more heat than ever. We're forced to take these stats with a grain of salt seeing how ChangeWave doesn't explain its surveying methods in its overview, but we've no reason to doubt the findings that 73 percent of corporate users are doled out a BlackBerry -- the same as was reported in November of last year -- while only 18 percent get a Treo, down from 28 percent a year ago. Now granted, these numbers represent the percentage of devices actually issued, which we suppose could be quite a bit different than what employees would prefer to be issued, but we doubt the difference is enough to equalize these two. What now, Palm?

StyleTap, the folks behind the CrossPlatform Palm emulator for Windows Mobile have built a proof of concept version of the software for the iPhone / iPod touch. They're not committing to releasing any such product, and aren't releasing the software as a beta or anything like that at the moment, but the video demo of the software in action is certainly promising. All the apps are rather responsive, the device benchmarks a good bit faster than the Tungsten | T, and Apple's keyboard is even integrated into the proceedings quite nicely. Video is after the break.

We don't mean to harp here, because we understand how long it can take to get a phone through a government bureaucracy like the FCC -- not to mention that little issue of Sprint exclusivity -- but we were just a little shocked to see that the Centro 685 (the technical full name for the GSM Centro) was tested a hot minute ago. How long ago, exactly? Well, as early as May of last year, according to the test report documentation, though the label shows a first revision of December 11 of frickin' 2006. Ah well, nothing to get too worked up about; at least it's available now, right? Also notable is that someone in either Palm or the testing firm slipped up and made references to the Treo 800w in the label document, so yeah, we can pretty much gather that it's stone cold real at this point (as if there was any doubt).

We're used to carriers typically releasing conservative hues first and resorting to the more wild goods down the road in an effort to revive sales and reach new target demos, but for whatever reason, AT&T is taking quite the opposite approach with its Palm Centro. A gander at AT&T's business site for the low-cost smartphone reveals that "Obsidian Black" is the next stop on the Centro train following the initial launch in Glacier White, so if your job calls for green keypads to be kept to an absolute minimum, hang tight. Right now they're just listing it as "coming soon," but we can't imagine it's too far off.
