I'm a (now former) Alltel customer who transitioned to AT&T today. On Alltel I've had an HTC Wildfire for about 6 months now, and on AT&T I now have the HTC Aria. I love the phone, it's MUCH faster than the Wildfire, and has has a lot better screen. However, on my Wildfire I had the option to delete old SMS messages automatically, and limit each thread to a certain amount of messages. I can't find this setting anywhere on my Aria. Does it exist? Am I looking in the wrong area? Thanks for the help in advance.
