Today Verizon will issue another minor update for the ThunderBolt. This will however be major for those who have experienced random reboots, since it's supposed to fix them. This isn't Gingerbread either. Regardless of the fact that we've heard that the Gingerbread update will happen in June, and now it's July. It's simply not Gingerbread.
What is it then? Well, aside from fixing reboots, it brings a preinstalled cradle dock app, improved data connectivity, enhanced Call History view, improved Bluetooth discovery mode, the app menu can now be viewed in a tabbed layout, people search is enabled, Backup Assistant is in All Apps, My Verizon, V Cast Music and V Cast Videos are preloaded, and the NY Times website has made it onto the Web browser's bookmarks list.
