I'm really hesitant of Jailbreaking my iPhone 4 for a couple of reasons. 1. The last time I jailbroke my iPhone 3G, it was working fine for several months until I downloaded a free app from the App Store. My phone was acting very slow so I manually turned it off and then restarted it. After doing so it wouldn't go back to the Home Screen, it was going into this loop. Tried restoring the phone and was getting an error message from iTunes stating cannot restore. Googled it for the longest time on what I can do to fix it, no resolution... So I sold it to someone on Craigslist for $125 and a few weeks later he was able to get it working... I wish I knew what he did to fix it.... 2. I already have what I really want which is Tethering. I jumped on that nice App called Handy Light for .99 cents, PLUS I have NetShare in which both apps are now gone..... But I really do want to download other apps out there but it's just a little too expensive. I know if I jailbreak my iPhone I wouldn't have to worry about that. Decisions, Decisions..... hmmmmm... Your Thoughts and maybe some related stories?
