Android 4.0 sure looks like a decent update for existing Gingerbread handsets. HTC isn't all that sure about updating their current line of Android phones to Ice Cream Sandwich though; if you've got an HTC you might be out of luck.
Talking to TechRadar, HTC said:
"While our goal is to upgrade as many of our recent devices as possible, we are committed to maintaining every phone's performance and usability first. Please stay tuned for more updates on specific device upgrade plans."
That sounds a lot like some phones, notably lower-power and older top-of-the-range handsets, may be left out of an official upgrade. Of course that might be a good thing; you don't want a crippled device like the iPhone 3G iOS 4 update debacle. [TechRadar via Gizmodo UK]
