According to most reports, you should not have any more chance of 'bricking' the phone than if it was untouched. Applying the 1.1.1 update *should* just leave you with a 'factory default' sort of iPhone with all 3rd party apps and their installers wiped out. For a good rundown, see:
Engadget's Update fact & fiction post
Here's part of what it says:

Most people with a jailbroken iPhone will end up with a "factory-fresh" iPhone after the 1.1.1 firmware update. Your mileage may vary, and isolated incidents of bricking have occurred, but most people are just going to have a 3rd party-free, AT&T-only iPhone in their pocket when the day is through, and bricking seems to be just as common for a virgin iPhones as for jailbroken ones.
