Official Android updates
  • The HTC EVO 3D is now ready for a maintenance fix called 2.08.651.2, which offers some nice improvements like allowing more Sprint bloatware to be uninstallable by the user, contact transfer via bluetooth, fixes for the lock screen occasionally freezing, and GPS enhancements. This update is available through a manual install. [via SprintFeed]
  • Speaking of the HTC EVO 3D, the bootloader unlock tool is now ready for your enjoyment on the company's fancy new dev site.
  • Android 2.3.4 is finally rolling out on T-Mobile's HTC Sensation 4G, and all users should receive the OTA update by the end of September at the latest. Aside from the standard 2.3.4 enhancements, Sensation 4G owners can also expect better battery life, additional software stability, extra touchscreen responsiveness, and improved "device reboots." Curiously, the refresh also promises better screen and photo resolution. All in all, this is the kind of firmware boost we love to see. (Thanks, Anonymous) [via TmoNews]
