Hi guys, I thought I had this one covered myself but I thought I'd ask for advice anyway. I guess you lot know the plans better than I do.. I'm visiting the states for 2-3 weeks in a couple of months and want a SIM so that I can still use data on my iPhone 4 (checking mails, a bit of browsing and accessing my network's website to send webtexts back home for free) I was going to order an AT&T go phone SIM from ebay and use that but from what I've managed to find out, there's no data plan. Meaning I have to pay $4.99 per MB? AT&T is advantagious for me as my uncle, who I'm staying with is on AT&T meaning he wouldn't pay a fortune to call me and visa versa.. I dont mind paying $60 or so aslong as I don't get ripped off for data by the MB.. If it makes any difference, I'll mostly be in Michigan and Chicago Thanks for any advice.
