So I tried to do the nice thing and get my mom an Iphone (3gs). Unfortunately its too much phone for her. I still need to add her on my family plan, which means I can get a subsidized phone. I have a Motorola RAZR that I will give her to use instead, but was wondering if it makes any sense to get an Iphone 4 for backup or to sell for profit? Or is there any other AT&T phones that are worth getting? I have an Iphone 4 already that I use. Thanks!
