I tried to install the Yahoo IM application. It downloaded and connected okay, but when it tries to access my buddy list, it reboots my phone. I tried to test the web browser to make sure I have a connection, but apparently I don't. I'm able to access my e-mail to read messages, but when I try to send one, the phone freezes. I don't know what's wrong. Please help! (FYI, I have Vodaphone.)
