Sony Ericsson T616

Has anyone else had problems with this phone's reception on the cingular network? I had the phone for 3 days, and I loved the features and design, but the signal kept dropping, and i'm an agent for cingular wireless, and my t720 works so much better as far as reception. i couldn't even get full signal in my store, but with almost any other cingular phone, i can. It's a shame that such an awesome phone has to have that downfall...
