Just asking. I was also considering doing the factory reset because of multiple issues like everybody else has mentioned.
For the first time, I went to look at the cards on the Thunderbolt (never had a need to take them out before) and saw that my SIM card seems almost "melted".
Does this seem to make sense to you? The phone does seem to run much , much hotter since the upgrade (and I'm following another user's recommendation to replace the battery after noticing the battery seems to not be holding a large charge and looks like it's "ballooning" in the middle).
Anybody else have what looks like a scorched or melted SIM card?
