Verizon has begun to roll out its first update for the HTC Thunderbolt after being delayed due to unspecified issues. The update addresses bug-fixes including better EVDO support and improved GPS performance along with stability improvements for data oriented applications. The update pushes the build numbers to 1.13.605.7 with baseband 1.16.00.0402w_1. The update is available by manually checking for updates on the phone, but Verizon has yet to update its support page to reflect the rollout.
