Downgraded, now internet won't work
 

Ok I was using the DCD 3.01 build with the 3.35 radio and my internet was working fine. Now when I flash back to the stock verizon ROM (and stock Verizon radio) I'm not able to connect. I've tried soft-resetting, hard-resetting, dialing *228. My epst and MDN settings are correct as well as my A-Key. Any suggestions? Tech support doesn't seem to have any ideas. I've heard that removing the data plan and readding it to your device can fix this, but it won't let me remove the data plan from my device as it says it's required.
