Data Connections Stop Me From Recieving Calls!

[mr_cheerios]

Hello all, I have been pouring through this and other forums like it for days now. I have been experimenting with different ROM's for a couple days now, and I need some serious help... I love this NFSFAN Bell ROM, but I use this phone for work, and I need to have my two email accounts connecting regularly to my data line to check for emails. I prefer to leave my data connection on 24/7, and before I modded my Bell HTC Touch I could do that no problem. But on this ROM if my data connection in on, I can't recieve calls because the data line won't make way for the phone signal in time. Help me please, I have seen many fixes and have tried lots of them and none of them seem to have worked. The phone call shows up on my phone in time, but when I hit answer it just waits for like 10 seconds until it goes to voicemail, and then my data connection closes.

I have Radio version 3.42.50 (obtained from the official Bell update) and am using NFSFAN 1.13.V2.
