z4Root 1.3.0 apk
Place the file in your sdcardrecommended the root(top folder of sd card)
Install with your existing package installer, let it run it's thing and reboot and verify you have the superuser Icon in your app drawer.
If you like 2.1 then go ahead and flash it now, but if you're holding out for 2.2 it's always hit or miss wether the 2.2 OTA will be pushed to your phone so just wait the extra day, we should all have or be able to get the official 2.2 OTA or SDK.
