I've been reading through all the posts about jailbreaking pluses and minuses. I'm ready to make the leap. I'll be using purplera1n. I currently have many apps from iTunes that I like and hold a lot of data in them. A few questions: 1. Will running purplera1n cause me to lose all the data in my apps? Will I hve to reinstall apps from iTunes? When I moved from my 3G to the 3GS I had to re-download 70% of my apps when I restored my new phone (versus using the last backup). 2. If I have to do a restore to take the phone back to it's factory settings, will I lose the data in those apps? 3. Do you have to do a restore every time there is a firmware update? In other words, will I lose all my data every time there's a firmware update? 4. Once the phone is jailbroken do you continue to sync with iTunes? Thanks for you help!
