The financial unveiling continued apace this past week, with both carriers and handset manufacturers announcing Q4 2007 - and, in some cases, whole year - performance figures. Unlike the week prior, however, it’s been a mixed bag of the record-breaking and the depressing: Verizon Wireless showed revenue up 13% (though a $1bn class-action suit over disputed early-termination fees soured their week), T-Mobile gained over 3.6m net new customers in 2007, while Parrot was coy with figures and merely claimed “sales gains“. Sony Ericsson shipped an impressive 103.4m handsets over the year, despite reduced Western Europe & North America markets, and while HTC couldn’t match those numbers a high average selling price of $350 a handset pushed revenues up 34.7% to around $1.21bn.

No such luck for Motorola who, despite taking top-spot for non-touchscreen Windows Mobile handsets, are considering selling off their cellphone business. They’re probably eyeing up the FCC enviously, as the government agency rakes in the bids for the 700MHz auction: most interesting bid so far happened on Thursday, tipping Block C over its $4.6bn reserve and guaranteeing the open-access clauses Google was so keen on. Elsewhere in the ether, Sprint’s Xohm team and Clearwire finally reached an agreement on network architecture standards, and roaming negotiations are making “significant progress”.

In software, images purporting to be HTC’s TouchFLO 2.0 UI for Windows Mobile hit the net, and we saw screenshots of Windows Mobile 6.1 itself which, if anything, prove that graphical overlays like HTC’s really are necessary for the OS. Palm released a ROM update for Sprint’s Treo 755p (which, like all updates, left some users with several errors), and Android developer workshops left some wondering if Google’s computer-centric attitude toward platforms had condemned the mobile OS to only the top-tier of smartphones.

Concerns, no doubt, that Nokia would love to cash in on; not only did the Finnish firm see their US-spec 8GB N95 get FCC approval this week, but they made a $153m bid for Linux OS developer Trolltech. They’re also promising to demonstrate their update to S60, complete with Touch UI, at the Mobile World Congress later this month. Meanwhile, Garmin unveiled their nuvifone, an iPhone-rival that seemingly takes GPS just as seriously as it does cellphone duties; expect major coverage of this in the run-up to its estimated Q3 2008 launch.

Speaking of the Mobile World Congress, our man Vincent Nguyen will be flying out on the 7th to attend the event for PHONE Magazine. He’ll be meeting with Sony Ericsson, Nokia, attending the ever-interesting ShowStoppers event and then hitting the floor to visit the booths. You can check out Vincent’s show calendar here, and if there’s anything you’d particularly like him to stop by, let us know in the comments.
