Undoubtedly the big news of the week has been Apple’s iPhone SDK and Exchange announcements; not only has the company shown developers exactly what the SDK is capable of – thanks to some big screen demonstrations from their software friends – they’ve made it available for free download.  Apple have also managed to make Exchange sexy (well, almost), sending Microsoft back to the drawing board to come up with an implementation for push email and synchronisation that’s as elegant as the cellphone itself.  Even news that multitasking won’t be possible for third-party apps isn’t enough to take the shine off; perhaps that’s the goodwill a $100m developers fund gets you!

Meanwhile, we spent the first part of the week revelling in the cellular goodness on show at CeBIT 2008 in Germany.  Our correspondent there, Milena, did us proud, with hands-on photos with Samsung’s G400 Soul, ASUS’ ZX1 Lamborghini collaboration, and some telling images that suggest Sony Ericsson’s XPERIA X1 is coming to AT&T.  Sadly it wasn’t all fun and games for everyone at the exhibition: Meizu were apparently too busy protesting that their iPhone-a-like M8 cellphone isn’t an Apple clone, to sort out certain “patent discussions” that temporarily saw their booth closed down by German police.

Talking of the XPERIA X1, worrying speculation began early in the week after Sony Ericsson’s own release-date database suggested the handset wouldn’t ship until February 2009.  Right now we’re keeping fingers-crossed that it’s a case of temporary data and that SE will deliver the device in mid-2008 as originally promised.  Something far further from the stores, though, is the rumored PSP phone; this week a Sony Ericsson patent for a touchscreen cellphone with haptic feedback and PSP gaming mode showed up, adding fuel to earlier talk of the device.

Elsewhere, MobiTV picked a fight with HowardForums after posters there were inconsiderate enough to discuss the media company’s shocking lack of security; rather than thanking people for pointing out that storing your feed urls in an unsecured text file is little discouragement to those wanting free TV, MobiTV’s legal beavers instead threatened to get HowardForums’ ISP to pull the plug.  Of course, as soon as the media backlash began, MobiTV’s president stepped in to reassure everyone that, as a “leader in new media”, they’re wholeheartedly behind resources like HowardForums, and meant no harm.

Ironically, as Apple were announcing Exchange email support, RIM quietly attempted to take HTML messages off their upcoming BlackBerry server update.  Motorola, meanwhile, lost a Chief Marketing Officer – but did he walk or was he pushed? – and gained a single cent share increase from it.  Happier times, though, for Nokia, who have finally shipped the US-spec HSDPA N95 8GB (albeit at a whopping $779, since no carrier has picked it up yet), and who have also signed a deal with Microsoft to bring the Silverlight streaming video service to S40, S60 and Internet Tablet devices.  It’s another slab of irony that there isn’t actually a Windows Mobile version of Silverlight; they’re expecting that sometime in 2009.
