I've just got a 3g so I can jailbreak and unlock it to use my vodafone sim. So far I've jailbroken it using Pwnage Tool, found my wifi network and connected to it and the wifi signal has appeared in the top left as usual but when I try to use safari or cydia it says it is not connected to the internet. This wouldnt be such a problem except that I need to use cydia to use ultrasn0w. Does anybody know whats wrong or if i can unlock it through my mac without having to use the iphones wifi? Any help would be greatly appreciated, thanks!
