I had a SE W600i but found that too bulky after using SE T637 & T617 for a number of years now. When cingular started carrying this phone, I jumped on it !!The phone's lightweight, fast & very stylish. I hate the cingular branding though. Every now & then I hit the orange cingular key on right & it takes me online & cingular charges me a nickel. Highly annoying.UPDATE: 11/27/2006I used DaVinci client 16.9 to flash the phone using the supplied USB Cable. It was really easy & completely worth it !! No more annoying cingular BULL***T !Just read today that from 11/27/2006 a law goes into effect which allows customers to legally unlock the phones so they can be used with other providers. Will look into it some more.
