I just purchased an unlocked 6620, and want to use it with T-mobile. Normal calls and text messaging and the like work fine, but I can't seem to be able to use tzones. Do I need a different browser? I've set my connection settings exactly the way it lists on t-mobiles website. Am I possibly just missing something?
Thanks in advance for any advice.

A few more developments. I can receive email through gprs, but I cannot send, and I still cannot connect to any sites.
