how do you turn ipod touch into a phone with number that people can call you? my phone reception on my college campus sucks. but the wife is great... i get wifi everywhere. i cant switch companies cus im under contract and i dont want to pay cancellation. i have a dumb phone cus i only text and maybe call on my phone. i have an ipod touch and ipad. also, will any app available for iphone also work on ipad and ipod?
