I recently jailbroke my iphone 3G and found that I didn't really know what to do so I un-jailbroke it, however I found that I couldn't add any apps to my phone because lots of blank icons kept appearing. I then jailbroke it again to see if there was anything that I could delete to fix the problem, nothing was there. I restored it a few times on iTunes but that didn't do anything so I then used the remote wipe function on Mobile Me. It's been doing that for about 3 weeks now and I have no idea what to do. I've had it since February last year so I don't know if I can take it into the apple store, please help!
