Data connection lost on Tilt 2

I built a ROM in BuildOS from PPCKitchen. Basically, WM6.5 with no bloatware and HTC Sense 2.5. I had to go and manually add the connection, but it doesn't say 3G nor does my gps work. I suppose I will have to keep flashing it till I get it right. lol... It's the first time I do this...
