I own a rom'd Sprint Hero and love it. I am looking to buy my girl a similar type phone but on AT&T or T-Mobile. I want a phone similar to a Hero since they will probably be around $100 or so used. I was looking at the G1, but want to know what else is out there. The reason I want it on those carriers is cause I want it pre paid, since she really doesn't use the "phone" to much. You can still use wifi to browse and use the app market right?
