I have a jailbroken iPhone 3GS which I have powered off completely and rebooted several times using Blackra1n, today however the same process no longer works!! When I click 'make it ra1n' the GeoHotz picture comes up as normal, after about 30 seconds or so it restarts again and comes up with the 'Connect to iTunes' screen, it just does this over and over! Anyone else having this problem? can anyone help? it was working fine up to today!
