We just released a new version of the Gmail app in Android Market, so Gmail updates arenít tied to Android version releases anymore. Now you can get new Gmail stuff faster without having to wait for system updates.
If you are on a custom ROM where the signature of the gmail app is different, then you will have to do the following first:
- adb remount
adb shell mv /system/app/Gmail.apk /system/app/Gmail.apk.bak
- adb uninstall com.google.android.gm
