Does anybody remember that one post that teaches you how to get the 3G plan for the price of the EDGE Plan by just switching the sim card??? Well, I tried that trick and now I just received an email and a text from ATT saying: "Our service records indicate that you are using an iPhone 3G with a data plan designed for other devices. To avoid unexpected data overage charges and enable Visual Voicemail, please contact your telecom manager, or an AT&T representative at 1-800-331-0500. Thank you for choosing wireless from AT&T. We appreciate your business." Sincerely, AT&T Customer Service Did anyone that tried this trick get this message?
