It is not clear from the statement below if when I backup using Mybackup from market will backup everything on the phone. Additionally once the update is complete, will the apps and all other data functionality be restored? Does Mybackup store the backed up info on the SD card or to the PC? I have only had this phone for a week and I've had no issues with it but obviously want the latest and greatest but not at the expense of having to spend hours putting the pieces back together. Mine is a Sprint Hero. "Any additional software or settings provided by your mobile operator or company will be lost.
