Hi all, I just bought an iphone (second hand, in as-new condition), which has been jailbroken and has 3.0 firmware installed. However, when I charge it or connect it to the computer, it just shoes the Apple icon on the screen and the swirling "loading" thing, and after a little while of this, it starts all over. I am very new to this and am not sure what the problem is. I am running Mac OS X 10.5.7 on my Macbook, which I believe meets the specifications, and have updated iTunes to the newest version. Can anyone help me out with this? Thanks so much.
