Huh and here we go. 4 Reasons Why the HTC ThunderBolt ICS Update Could Be Late 1. HTC and Verizon completely missed the July upgrade window for the HTC Rezound and then pretended as if nothing happened when it released the software in early August instead. It’s clear that neither company has any problem breaking update promises. 2. HTC’s Facebook account has stopped telling ThunderBolt owners that August is still in the cards. Instead, it has been extremely vague about the update’s arrival. 3. Verizon’s website remains without an HTC ThunderBolt ICS update changelog, something that is usually posted ahead of a widespread roll out. 4. Verizon may have learned that hitting the deadline for the sake of hitting the deadline probably isn’t as smart as it sounds. The Droid RAZR and Droid RAZR MAXX updates were released on the last day of their promised update window and both pieces of software are plagued with bugs. So, it’s possible that HTC and Verizon want to avoid something similar.
