You're backed up? You could do the entitlement hack..free WiFi tether through the vzw app...it chews through data though...so if you're not unlimited..that's something to think about...
You could run roms...idk anything about that though....
You can change your boot animation..this too...I don't know anything about...
I'm backed up, running the entitlement hack...and that's it...lol....
When you root, you can use apps like titanium backup to store your apps and info on your SD card...
So if you have to wipe everything off of the phone..all of you data will be put right back onto it with the app...makes it a lot easier..at least to me...
I did my first factory data reset last night...and all of my apps and everything were in my tibu file..quick, painless ..I didn't have to set up anything...it was already there....
