Restore data wipes?
Hello all. I currently have a jailbroken 1.1.1 iPhone, but 99% of my applications I download with Installer simply crash out as soon as they start. I think this is possibly because of 1.0.2 apps and stuff that were left "unresolved" when I started up. I'm considering doing a restore or something to wipe the slate clean, but I don't want to lose all my data (numbers especially).
If one does a restore, how much data is lost? If I sync with iTunes, but don't have contacts snyced with windows mail or whatever, will it still save them? What do I need to do to maintain all my numbers and contact info?
