http://www.walmart.com/ip/Tmobile-30-Wireless-Airtime-Card/15443357 okay so Walmart and Tmobile made this deal happen. $30 per month for unlimited data and 100 minutes. my question is, if I buy unlocked iPhone 4s from apple, wil this plan work or is there a trick? it sounds too good to be true. my other alternative was a 2 year contract with ATT, $55 per month for 200mb data, 200 minutes - much more expansive than actually getting the above deal. can someone advise? thanks.
