I'm finally getting an iPhone 4 tomorrow, and I was wondering would it be better to use one of the mainstream jailbreaks such as limera1n or greenp0ison or use pwnage tool? I have been using pwnage tool for my 3G and a 3GS too, both have worked really well. I have just restored my 3G to a custom firmware of 4.1. Are there any differences to the way they both jailbreak? Or do they both rely on the same exploits? I know that you can use pwnage tool to preserve baseband (which is why i've used it so far) but with my iPhone 4 unlocking i wont be concerned with that. There are endless threads about "limera1n vs greenp0ison", none I can see that involve pwnagetool.
