Hi all, I have an iPhone 2G and it has served me well so far. Nevertheless, a friend wants to buy it and I have been tempted to get the 3GS model (mostly due its performance and tether capabilities). This seems to be the perfect time to move on. I am not finding an old discussion regarding what to do in these cases. I remember someone posted hints/discussions like "I got quite a few apps and would like to keep them" or "How to wipe it out for the new owner ?" . I appreciate if someone has that link or else. Thks a bunch !
