I have an unlocked iPhone with no data plan on T-Mobile USA. The voice works fine. I want to be able to use some data (maybe a couple times a month) but I don't need a data plan. Is it possible to use a dial-up internet connection (I have a dial-up account) to grab a couple things off the internet via the voice channel (i.e. make a call) every once in a while? (I never use up the minutes and I have unlimited nights&weekends) Is there an app or package for that?
