Hey, I've had an iPhone 3G for a little while now, it's time to take it to the next level! I want to jailbreak it on the 3.0 OS, is that possible? I would appreciate links! With that said, what's a good way to make sure that battery life is kept the same as before it was jailbroken? I noticed that difference between an unjailbroken and jailbroken 2G iPod Touch! And here is the most important question: Is it true that once you've jailbroken, you risk your sim card, meaning at some point you need to purchase a new one? - I'm not unlocking, just jailbreaking... I'm happy with ROGERS WIRELESS, carrier in Canada who I am through and purchased the iPhone through!
