I have 3G with baseband 5.12.01. I don't have a sim card so I can't access the phone to use jailbreak me. Is there another way to jailbreak? It's running 4.0.1.
Can I point it there even if I'm running 4.0.1?
And is it worth enabling multitasking or will it make my phone too slow.
Thanks
I jailbroke an iphone 3g without a sim card. All you need to do is get on wifi.
