Connected to Verizon, or T-Mobile and waiting on an Ice Cream Sandwich update to your Android device, well, you might enjoy some leaked scheduled update maps. Of course, as usual, this isn't confirmed by either provider, so for now it's just a rumor.
Verizon should be rolling updates to the following handsets soon: HTC Rezound, Motorola Razr, Razr Maxx, Xoom 3G and Xoom 4G. The "pull" dates for those handsets are between May 9 and 23, whilst ROMs for the Xoom have yet to be determined. For those on T-Mobile, Samsung's GALAXY S will receive ICS after May 14, with teh HTC Amaze 4G and Sensation 4G getting their ICS updates after June 16.
Of course, these dates and models are always subject to change, especially when it comes from leaked schedules.
