Carrier Drops after Unlock

[theguywiththeface]

I previously had a 3G(jailbroken) and smashed it to pieces so I bought a 3GS. Used it without jailbreaking/unlocking for a few days then decided to go about personalizing my phone.

I used blackra1n to jailbreak my phone. After jail breaking I decided what the hell, why not unlock as well since Sn0w was so conveniently installed for me.

But since unlocking I've noticed a lot of no network messages randomly in area's i know have good signal otherwise.

I know my phone is picking up on the Bell/Telus GSM network so I've forced the phone to use Rogers Only to see if that helps. I've only experienced one drop off since that and I'm not sure if it was due to the fact the building I was in is bad for cell signal.

Has anyone else experienced random network drops while using Sn0w?

I've got Base Band 5.11.7 and Rogers 5.0 for my carrier.

If others are experiencing similar problems, can I do this to fix it?

1. Restore Apple's Factory Firmware
2. Re-break the phone
3. Not Unlock the carrier

Thanks for your help!

Issue still occuring. I'll go from full bars to "Your selected carrier is no longer available" back to full bars in a matter of seconds, Im in a location that normally has constant strong signal.
