So I'm on my commute home and my iPhone 3G starts to lag pretty bad, so I turn it off then back on. Well, to my surprise my AT&T symbol was shown as 'AT&T' with the little inner quotes. It stayed that way for about 15 minutes and then just switched back! Also, my two email accounts had magically become empty and had to redownload all my emails (up to 100). WTF?! Anyone ever have this before?
