Got my Verizon HTC Incredible 2.1 to stop the annoying system update messages.
these are the steps I used:
download android sdk, unzip and copy all files and folders to c:\sdk
root phone with unrevoked3 (see youtube)
Boot into Clockworkmod recovery (dwn vol btn + pwr btn)
press volume down to select "Recovery", then press power.
at Clockworkmod main menu press volume down until "mounts and storage" is highlighted and select it with the optical joystick
then select with the optical joystick "mount /system"
on your computer click Start > Run, and type CMD to open a command prompt
at the command prompt type cd\sdk\tools
at the next command prompt type adb shell
type mkdir /system/app/disabled
type mv /system/app/SystemUpdater.apk /system/app/disabled/
(notice caps in SystemUpdater.apk)
(SystemUpdater.apk app is now located in the disabled folder)
at Clockworkmod partitions menu select with the optical joystick "unmount /system"
press power btn and select "reboot" and unplug the USB cable
Good Luck.
