Clean it up and send it.
I lucked out with mine. I have only had one, and the few problems that I have had were caused by myself either with new program installs, or updating the OS.
Like you, I too was excited with my first Blackberry. I originally had the Palm Pre, which turned out to be a brick. Class problems, and after all of the setup I had done, there was no way I was going to have to go through any of that ever again, so I upgraded to the 9630.
Since then, I have also convinced two of my friends to upgrade their phones to Blackberries, and they too enjoy the phones.
Good luck, and keep us posted!
