I sold my 3GS a couple weeks ago when I got my new iphone 4, but when I do the find my iphone trick on mobile me, it still shows my old 3GS in list of devices along with my new iPhone. Why is this? Before selling it I restored to factory settings and installed ios4 clean on it. I then activated my new phone redering the sim pretty useless in the old one. Now granted it won't locate the old phone, but for some reason it still shows it. Penny for you ones thoughts.
