Hi, my parents decided to buy me an iPhone 3GS 8gb. It will arrive in a week. I already own an iPod Touch 3G 32gb that's jailbroken. Can I jailbreak this new iPhone? What will that do to the phone service, I don't want it unlocked. I only used 6gb on my iTouch and I had it for 11 months, so 8gb won't be a problem? I'm new to this iPhone buisness, so thank you in advance.
