All you owners of a Sprint Evo 4G rejoice for there is an update upon you. It goes by the name 3.70.651.1 and it bringeth some fun items including: Blockbuster (including WM DRM 10), Kindle eReader, Preloaded try/buy video game: NOVA from Gameloft, Sprint Zone update, Latest Telenav, Latest VVM App, Latest Sprint TV app, SWYPE Keyboard, and Scan Now Widget for 4G. You can wait for the update as it reaches your area, or update manually.
To update to this newness manually, begin by downloading the file at this link: [renaming it update.zip]. After that,
1. Reboot to recovery mode by first turning the phone off, then pressing the volume down button, and press also the power button. Your screen should boot to a white screen with three Androids on skateboards.
2. Use the volume button to select RECOVERY and press the power button one more time. Your Evo will now reboot into recovery mode. You should see an image of the phone with a red triangle and an exclamation point.
3. Hold the volume up button and press the power button. Choose applysdcard:update.zip and let the magic begin.
These instructions should be fairly self-explanatory, but if you have no idea what any of them mean, we suggest stepping on into T-Mobile for some support. Hopefully they'll be ever-so-kind and lend you a hand on your way to update world.
