Can anybody recommend a reputable, informative and yet simplistic site that explains how I can effect an untethered jailbreak on my iPhone 3G 4.2.1 ( EDIT: New Bootrom) using Windows Xp. Any suggestions gratefully received as it appears to be a bit of a minefield of differing advice out there ! Apologies if this is an oft repeated question but my iphone, in its stock guise is driving me mad !! Any opinions of "" ?
