Leave iTunes Running while you run Limera1n! I tried it without iTunes running 3 or 4 times, rebooted the phone god knows how many times and nothing worked. I tried it with iTunes left RUNNING while I ran Limera1n and it worked like a charm. This was on an iPhone 4.
Hope that helps!
oh yeah make sure you connect to wifi before you run limera1n... it'll make your life easier lol
