lost data no internet! please help

[grashoper]

Hello everyone. I'll make this quick and easy question. I have successfully updated to 3.35 radio, and tried several different custom roms in the past 2 weeks... At some point, i lost my internet connection, went back to stock rom successfully, and tried entire process over with and without the new radio (depending on which rom i tried according to instructions) and still no internet. I have spent literally over 4 hours on the phone with bell (Canada) to no avail. Only other option is to beat it with a hammer. I have noticed a couple people have had the same problem.. i have read these and XDA forums for hours and hours and hours, to try and fix this and get my Data connection back. tried almost every Rom i could find... to no avail. I'm just wondering if anybody had a sound fix for getting the Data connection back working again before i go to the store i got it from and freaking out and trying to get a new phone, or sending it off for a warranty claim which they say could take 6-8 weeks. Thanks for your time.

Chow.
