Official Android updates

HTC Rezound: Build 2.01.605.11 is now detailed on Verizon's site, which means we'll see it hitting OTA very shortly.

Samsung Epic 4G Touch: Sprint's rolling out a lot of security updates right now, presumably to remove Carrier IQ software from its lineup. The Epic 4G Touch's bug fix is beginning to hit units now, bumping the phone's software up to EL29. In addition to a "security update," EL29 also addresses CMAS (Commercial Alert System) and the ability to dismiss multiple calendar alerts. [PhoneArena, AndroidCentral, Sprint]
Sony: This spring, around the same time its Xperia lineup receives ICS, Sony's tablet offerings -- the P and S -- will also be beneficiaries of the upgrade. [TheVerge]
