I've recently come into a good deal on a refurbed first gen iPhone, and want to give it to my mom as a gift for Christmas. She is currently an AT&T customer, but I'm not sure she's going to want to pay the extra 20 bucks per month for the data plan or not. So my question is, should I jailbreak and unlock it before I send it to her? She'll probably not get into using themes or any non app store apps, but if she wants to use the phone without the data plan, it's going to have to be unlocked. On the other hand, it's possible she may want the data plan. If I unlock and she decide to pay for the data, will she be able to just plug it into her old 12" Powerbook and run through the whole setup of upgrading the account?
