Though it'd originally been pegged for the second quarter, it seems HTC's bumping that up a smidge with the launch of its new flagship -- the Incredible S -- in the UK this week. Pre-orders are going on as we speak with shipments promised for tomorrow, but there's a catch: rather than shipping with Gingerbread, the phones will come with Froyo to start with an upgrade to Gingerbread promised for the near future. Buyers, we've got a little homework for you: if you're feeling adventurous and in a warranty-voiding mood, try to figure out what's going on with those auto-rotating capacitive buttons, alright? 
Weary Epic 4G owners, wonder no more about your phone's long-overdue update to Android 2.2, because the rumors were true: it's nearly here. Sprint has thrown up a support page detailing the build EB13 upgrade that will kick off on February 21st, saying that all customers "should" have it by the 25th through a phased over-the-air rollout. Besides the usual Android 2.2 goodies, the update promises "GPS enhancements," which is something that pretty much every Galaxy S owner around the world is always on the lookout for with every new firmware version. Of course, we'll believe this all when it actually starts happening -- but it's a good sign.
