The Android 2.3 Gingerbread update for the Evo 4G will bring some much needed bug fixes

    * fixes for the infamous SMS bug
    * fix for multiple Gmail account syncing
    * fix for a battery that refuses to charge anymore when discharged beyond the low battery threshold
    * A hilarious to all non-Spanish-speaking users fix to the SMS app that reads "Me instead of Yo in SMS thread conversations when set to Spanish" ("Yo" means "I" in Spanish)

This is the 2.6.35.10-htc-kernal_and18-2-signed.zip file you are downloading, make sure to read full instructions on installing this kernel to your HTC Evo 4G Phone
To flash it, follow these instructions:

   1. Download the OTA
   2. Rename the file "update.zip" (the actual file suffix needs to be .zip, make sure .zip isn’t just in the name [eg, not update.zip.zip])
   3. Place the file on the root of your SD card (the main directory you see when you mount your EVO as a disk drive)
   4. Reboot into recovery (power off, then hold volume down when you hit then power button to power back on)
   5. Select recovery from the menu with the power button, then, when the sign with the exclamation point appears, press Power+Volume Up at the same time, and wait (up to 30 seconds).
   6. Now, select bootloader with the power button, then scroll down to Recovery and select it with the power button.
   7. Finally, select "Apply sdcard:update.zip", wait for it do its thing, then select reboot. The fresh reboot may take a while and several restarts to apply – so be patient.
