Would you look at that - only hours after we leaked the long overdue update that, most importantly, fixes reboot issues, Verizon opened the flood gates and is now pushing the 74MB download over-the-air to HTC Thunderbolts all over the country.
The update version number is 1.70.605.0 and, unfortunately, it's not Gingerbread (remember how we told you that the June 30th Gbread rumor had to be fake?). The full list of improvements can be found in this PDF document, which I will include below for convenience:
Verizon Wireless is pleased to announce a new software update,
Build Number: 1.70.605.0 Baseband: 1.39.00.0613w, 0.01.69.0613w_1,
for your ThunderBolt™ by HTC.
