Earlier in the month, HTC has announced on its Facebook page that it was planning to wrap up the ICS upgrade rollout for several devices by the end of August, namely for the HTC Thunderbolt and the HTC Desire S. Given how tumultuous the road to ICS often is, in which delay is but the name of game, some may need to take the news with a pinch of salt.
It’s a different story for the HTC Thunderbolt, however, as an official ICS ROM for the HTC Thunderbolt has made its rounds on the internet. The leaked firmware is a good sign that the ICS roll out for Verizon’s once flagship offering is imminent, provided all the glitches and bugs that users are reporting can be dealt with in a timely manner.
While the leaked file works great for some people, others are noticing several problems. The common issue that folks have is the deteriorating battery life. Aside from issues like the loss of BT, the performance seems to be taking a hit as well. Again, we’re seeing conflicting reports about how well the leaked ROM is running. So you should keep this in mind if you do decide to take the plunge and install the leaked ICS.
