So I went to setup my AIM on the G1...and set up my regular screen name. I decided later that I wanted to use my secondary one instead (one I designated with my previous phone to be my "cell only" screen name). The problem is that I can't find a way to remove my initial screen name account and replace it with the secondary. Within the "IM" section, I checked the menus, but saw no option of adding another screen name or editing the account(s) I already have set up. Anyone have any insight or advice?
