Is your phone detecting your sd card? Can you download stuff to it? Can you transfer apps to it?
Did you try a different USB port? The ports on the back of the computer tend to work better.
Did you root your phone and forget to install the sd card fix found here?

If you are rooted, get a root explorer on marketplace such as "es file explorer," enable superuser access in the settings and go into /preintstall/app and delete. I did this when "lets golf 2" kept reappearing on me.
I assume you're using stock. I haven't used the stock rom in a while, but I vaguely remember when viewing all the apps, hit the menu hard key and there should be something to swap those out.
My dad's stock phone has randomly made loud buzzing noises during his calls. Sounds similar to speakers that make a buzzing noise before a cell phone call comes in. It won't stop until he hangs up. Has happened 3 time within the past week and a half.
