While there are already vague Android update plans for Verizon-connected Samsung devices, a leaked screen from somewhere within the Big Red bunker has offered up some more details. It looks like the Rezound, Droid RAZR and RAZR Maxx are closest to the upgrade finish-line with testing likely to finish by May 7th for the HTC model and May 17th for the Motorola duo. According to Droid Life, Verizon’s Motorola Xoom (you know, the Android tablet) is getting its update direct from Google, but it hasn’t been deigned worthy of a concrete release date. A handful of software updates are also pegged for the likes of the Bionic, Thunderbolt, Revolution, Galaxy Tab 10.1 and Xperia Play, but they look likely to be more incremental than outright OS upgrades. For those interested in some new firmware numbers, we’ve included those update details after the break.
