It looks like the success of the HTC Thunderbolt will be seen in the next couple of updates that are sent out. The bad thing is that I don’t mean that as a joke. The HTC Thunderbolt has been plagued with battery issues, connectivity problems with 3G and 4G, an SMS bug, and perhaps a lot more. As I said earlier, a lot of these problems should be corrected with a software/maintenance update. However, until that hits your device, you’ll have to endure.
Could your problem be unique? Could there already be an answer for your issue? We don’t know because we don’t know your exact issue. So reach down into the comments and let us know what problem is plaguing your HTC Thunderbolt. Hopefully there is an answer!
