kamak I'm in the EXACT same situation as you now. I'm on the 1.17 Bell ROM, my standby mode locks the phone permanently, and my internet does not work... You should pm me, maybe we can work together to get this fixed? I've been doing a lot of googling but no luck so far. For now set your auto sleep to never (uncheck it in the power settings) to avoid having to soft reset.
The username and password for bell is:
username: <10 digit phone number here>@1x.mip.bell.ca EDIT: or try <10 digit phone number here>@1x.bell.ca info here (sorry for the HF link, but it's information...):

password: <original 4 digit voicemail password>
But that doesn't work.
Getting closer...
I managed to flash the Bell stock ROM while keeping standby mode intact. Internet STILL doesn't work, but I'm working on getting that working (flashing Bell update ROM as I type)
So here's how I did it: Follow the Downgrade instructions here:

I couldn't manage to get it to STAY on 0.36 after I rebooted, but it DID say 0.40, so I was happy. I then flashed the Bell ROM, and voila! standby mode now works. It seems the CoKe 2.31 bootloader was staying intact with the Bell ROM, and this affected standby mode somehow.
Anyways, i'll post back later if I manage to get data connections working again, please do post here if you get it working too
