Hey, I've been told to do a factory reset to remove the lag and crashes on my SGS. It started after upgrading 2.1 to 2.2. But... I'll lose my data if I do. I did a backup using Titanium backup, and sms backup & restore. But I'm unsure if there are any pitfalls I should worry about when resetting and later returning the apps and data. If anyone has done this procedure (probably ) any hints and tips are welcome. Thanks!
