I'm looking to buy two ipad 2's - one for my wife, one for me - 64 mb version. Our phone carrier is T-Mobile and we use Blackberry 9700's - bad tethering possibilities without jailbreaking. How useful is the G3 option? We'll likely use G3 service occasionally for trips, etc., but not on an ongoing basis. I'm been reading a lot of discussion on this topic, but still can't make up my mind. I'm gravitating to G3 Verizon due to greater coverage, but the wifi option is enticing for its lower cost. I really don't know how often I'd sign up of a month's worth of G3 service. Not having owned an ipad before, I don't have any real-world experience to make a decision. Thanks for your help.
