Bell Canada HTC 6800 HELP Radio ver 1.37!

[Rocket976]

So I have searched around the forum and haven't been able to come up with a solid answer about how to go about upgrading my ppc 6800 I have rom ver 2.13.666.0 and radio 1.37.00 so basically I cant do much and my bluetooth is weak. No GPS either. So I have sort of figured out a few things so please correct me if im wrong.

To start I need to unlock my phone? Then I can install non cert apps, if im correct.

Then I need some sort of kitchen to choose the apps to add to the rom?

Then I need a prog to perform the flash or does the kitchen do this too?

Does it make a difference if im on Bell Canada network, will all my stuff still work? If not how can I make it work?

Sorry to sound like an absolute newbie but well I am.

Any help would be appreciated.
