Of course a battery does not store data, but I didn't know if the phone erased the data when battery disconnected. I hear too many wacky stories from folks losing data all the time and didn't know why. My iTunes doesn't work properly so backing up to the Mac in stead of the cloud hasn't worked in some time. * I ended up buying a battery off eBay and replacing it myself. Took 2 people/4 hands at one time to pry the screen up and to pry the battery loose. Works fabulously. * BTW, a great app I used to backup my contacts and email them to myself in a recoverable file format is MCBackupPro. Can never be too careful! Thanks, all! You're very helpful. Have a star spangled day!

Bunk. I only backup my contacts > and apps. My could shouldn't be full. So I guess I have 2 questions. > What to do about this backup issue. > > Thanks. > > Stacy >
