Wirelessly posted (Opera/9.80 (iPhone; Opera Mini/6.13548/24.871; U; en) Presto/2.5.25 Version/10.54) Hi all, i hope you can help me. Im going to be spending a month in the states and would like to use my uk iphone 4 for data, mostly skype and facebook. Is there a sim only pre pay card i can buy for ip4 that will give me maybe 1gb of data and a one month validity? My phone is factory unlocked. Completely clueless here so any help is greatly appreciated! Ps - will have access to wifi on evenings, just need 3G data during the day.
