Where have you been? If you had service with the former ATT, now you should have service with Cingular, so no more mmode, etc.
I use att wireless and i just purchased a new cell phone on ebay because att stopped selling cell phones. Everything works fine with my att service except for the internet. if i try to do anything that i would have to use the browser for it trys to connect to "T-Zones" the t-mobile browser and not "Mmode" the att browser. Its obviously meant to be a tmobile phone but is there any way I can still use a browser with this phone and my att services? If not how else could I get new ring tones? Thanks.
