Android 4.0 Ice Cream Sandwich has been long promised for the Verizon HTC Thunderbolt. HTC told us back in May that we should see something in June or July. Earlier this month HTC updated Thunderbolt owners again, moving their timeline to the end of August. It looks like they may just be on target after all.
Team BAMF has managed to get a hold of a leaked ROM for the HTC Mecha aka Thunderbolt. It’s build number 7.00.605.2 and running Android 4.0.3. Everything is fully functional in this ROM including 3g, 4g, phone calls, sms, mms and more. HTC Sense has been updated to version 3.6 which is a substantial update over the original Sense 2.1 that came with Gingerbread.
This ROM is near stock. The only modifications that have been done is deodexing, rooting, and an unsecured ramdisk. You can head on over to the official thread for full download details.
