Speculation regarding Windows Mobile 6.5, which is expected to debut at MWC next month, is fast and furious.  And how best to put speculation to rest than with screenshots of the upcoming mobile OS?

We’ve seen some screenshots of WinMo 6.5 over the past few days, and now we have a few more thanks to the friendly folks at the XDA Developers Forum.

The new screenshots show the updated Today Screen, the new honeycomb Programs shortcuts menu and a couple of screen grabs of IE Mobile 6. Sadly, there’s still no hint as to what the rumored Zune media interface will look like, so we’ll have to wait on that one.

T-Mobile USA has launched its new (and long-awaited) T-Mobile Shadow smartphone, an updated and redesigned replacement for the first generation Shadow. 

Rather than calling it the the Shadow 2 or Shadow 2009, as had been suggested in past months, T-Mobile has chosen to call the new smartphone the T-Mobile Shadow, the same name as its predecessor.  No points for clarity.

Built by HTC, the new Shadow runs Windows Mobile 6.1 Standard (non-touchscreen) and offers HotSpot@Home support, EDGE mobile data connectivity, up to 7 hours of talk time, Wi-Fi, and a microSD memory card slot.  Like the previous Shadow, the new smartphone has a downward-sliding dial-pad that pulls double duty as a SureType-style keyboard.

The T-Mobile Shadow is available in two colors: White Mint and Black Burgundy (shown). You can grab one now @ T-Mobile’s web site.

The first Firefox Mobile beta for Windows Mobile could come as soon as next week. 

On Mozilla’s Fennec (the code-name for Firefox Mobile) notes page for January 26, developers state that they are “targeting a Milestone release for the first week of February.”  The page goes on to state that the first beta will be targeted for the HTC Touch Pro (also sold in the U.S. as the AT&T Fuze).

This comes as a welcome surprise as previous reports had the first WinMo beta of Fennec scheduled for March or April.

According to a document obtained by MobilityToday, release of the Sprint Treo Pro has been pushed back until February 15.  The new Windows Mobile smartphone was supposed to have launched yesterday.

Apparently, nearly 2000 Treo Pros were sent out for the scheduled January 25 launch, but they’re to be locked up until the new February release date.  The document, which was directed to Best Buy stores, doesn’t give a reason for the delay.

Why would Sprint delay the release of a handheld that’s already in hand?  Software glitches?  Some OS update coming between now and February 15 that Sprint and Palm want applied in-store at sale?  Sun spots?  Who knows…
