I'm leaving for Europe next week and would like to use my prepaid iPad (T-Mobile) when I get there. Can someone give me the details on how to go about this? Purchased the iPad from Apple, do I need to get it unlocked? TMO said I would have to get a new SIM for my iPad and convert from Prepaid to a Postpaid plan. I'm thinking it would be easier to just get a SIM in Europe. I want to go back to my free 500 MB when I return in a month. Thanks for any help.
