PPC-6800 Not able to answer incoming calls - Soft or Hard Button

[davrodg]

When receiving calls on the phone (both with PointUI loaded and disabled), I can't answer the call, and notice the radio seems to downgrade the signal to 1x. I can neither hit the hard button or the soft button to accept incoming calls, nor can I hit ignore. I have upgraded my phone numerous times, using custom roms/stock roms, and am very comfortable finetuning my phone, apps etc. I have encounted a problems that may be hardware related, but wanted to check the forums first to avoid wasting my time at the Sprint store. I currently am running the beta ROM, but the same problem existed with the new 3.35 ROM as well (which is why I downgraded, thinking the radio version was the culprit). I have 3.27 and 3.16 Radio currently, which has the same issues as the 3.35. I don't mind doing a new rom again, but I don't know if that will resolve the issue. Has anyone else encountered the issue, and what was the resolution.
