I have a blackberry 8900 that is set up for Tmobile. Since I am in Thailand it does me no good. I need to put another browser on it but can not since the only one is Tmobile and they are always looking for a hook up that I don't have. What can I do?

We can't really help with the details you gave. My guess is that it isn't the browser.

What error messages are you getting? What carrier are you using? Is the phone unlocked? Do you have a BB data plan activated with your carrier?
