I'm going to Italy in May and want to use my iPhone 3g, 4.1 bb 5.14.02 while I'm there. I'm new at this but from all the reading I've done, if I jailbreak then use tiny umbrella, I can then find out what bootloader I'm on. If I'm on 5.8 then I can unlock easy and use GPS. If I'm on 5.9 then no such luck and GPS will be gone if I go up to iPad bb. Is this right? I'm trying to jailbreak via iclarified but their download link for redsn0w doesn't work for iphone 3g, 4.1. Do you think I should update to 4.3?? Thank you!!!
