I don't know if it's a limitation of Android or if I'm doing something wrong, but the market only recognizes apps I own if they're associated with the FIRST google account I sync the phone with. I had a little confusion when i first got the phone and made app purchases under 2 of my google accounts. I can only use half of them at one time, depending on which account I first sync to the phone (such as after a factory reset). VERY annoying!!
