Hey! I am looking into switching to Koodo...my Iphone 4G is locked to rogers and the back glass part is all shattered. It still works perfectly fine as long as i have a case on it. My questions are : 1) would it just be easier to buy a new iphone 4G from koodo? 2) can i do that without going on a contartact? 3) If i got it, can i just get a Talk and Text plan? I don't want a data plan. 4) What is Tab?
