Dude... A hole bunch of people are going to light this thread up about posting in the wrong place. Everybody learns the rules after they have been here a while. That being said, what you need to do is just flash another rom from your SD card. You can follow the directions in the following thread!

You could also just hard reset your phone. This will restore the rom that you presently have on your phone back to the way it was when you originally loaded it. Did active sync ever work for you on the rom you are currently on?
