I have iTunes 9.1(79) on my MBP. I have an iPhone 3G with 3.1.3 (7E18). I also have a wifi iPad, and the only reason I am really interested in jail breaking the iPhone is for tethering. Can I do this? Sorry if this has been answered a thousand times...I have no experience with it, and find lots of posts confusing at this point. Thanks for any help.
