So I am hopefully getting the iPhone 4 on the launch date, however I would like to give my 3GS to my dad for fathers day. Is there a way without jailbreaking/unclocking so that the 3GS does not have a data plan? We are on a family share plan. I thought the data contract was required with the initial purchase of the phone due to the subsidy, but now that I am upgrading to the iPhone 4 I should be renewing my 2 year data contract. Any ideas? Thanks!
