Geckos don't have shells, but Gekkos will -- and it looks like T-Mobile is going to be serving up an unprecedented level of customization for its latest Sidekick. Hiptop 3 is showing mockups of what appears to be T-Mobile's shell creation site, a special little place on the internets where users will be able to design their own Gekko (aka Gecco, aka Sidekick 2008, aka "please just release this thing already") skins, which in turn will likely be outsourced to Skinit for manufacture. Considering the Sidekick's line wild, crazy, and creative target demographic, it seems like a great idea and a potential gold mine of secondary revenue for the carrier. Who's going to be the first with an Engadget shell, hmm?

Tough time to try to hype a new skin for Windows Mobile, we'd say, what with juggernauts HTC and Sony Ericsson both trying to knock balls out of the park with TouchFLO 3D and the XPERIA's shell, respectively; that's not stopping ASUS from giving it a go, though. The Taiwanese manufacturer has chosen Computex as the stage to officially take the wraps off its "Glide" UI concept, the first shot of which we saw in the leaked shots of the P560 a few weeks back. Features of the shell include ASUS Today, a home screen replacement; Anytime Launcher, a straight-up app launcher; EziPhoto for photo management and EziMusic for a glorified media player. Nothing too groundbreaking here, but hey, can't blame 'em for trying to keep up with the Joneses.

The last we heard about i-mate's Ultimate line, the company was allegedly planning on "staggering" the release of the WM 6 Pro handsets, but it's been over two months without any news to report -- and now suddenly the tubes are alive with i-mate news: not only did the company announce the Ultimate 9502 and 8502 handsets today, UberGizmo is reporting that i-mate is working on a Foleo-esque "shell" for the line, with 1024 x 768 display, larger keyboard, and 80-hour battery. Unlike Palm's charming folly, however, the i-mate shell won't contain any processing power of its own, instead serving more as an extended dock for the Ultimate devices themselves. It's a pretty sketchy rumor, to be sure, but given the i-mate's topsy-turvy handling of the Ultimates, it's as likely as anything else.

We're personally of the opinion that the best way to cure iPhone envy is to... you know, buy an iPhone, but we understand there are plenty of reasons why folks might be forced to admire from afar. A lengthy contract might be stifling your inner free spirit, for example; maybe the lack of 3G is just too much to bear (YouTube addicts, we're looking at you). The aptly-named "WhoNeedsAniPhone" project seeks to ease the pain of this demographic -- likely a sizable one -- by using Flash Lite to bring the iPhone's key visual elements to touchscreen-enabled Windows Mobile 5 and 6 devices. Key goals for the release (which isn't yet available -- sign up to beta test it at the site) include a functional launcher, slide-style lock screen, and weather widget; baby steps, yes, but when you consider that the real iPhone's visual fireworks nearly match its actual functionality, that ain't a bad list.
