Hi so I want to buy a iphone 4g not 4s just the 4g online, then take my SIM card I currently have the blackberry torch (yes another blackberry girl switching to iphone..lol) but I wanted to know if thats possible, like if the sim card is the same size and if it will work. I think I have the exact same data plan that iphones run on (i'm almost 99% positive I do) so I'm not worried about extra cost's but...Does anyone know for sure if the sim card is the same size or if it would work! THANKS
