Sashimi works great if you take the time to set it up with all the cabs and reg files.
I use it along with Spb backup and never seem to have any problems.

Sashimi restores all the games/apps and registraions.
Spb backup is great for restoring contacts and email accounts and settings.
Together they make re-setting up your device painless and almost effortless.
