Upgrade from 2.x to 3.x on unlocked 2G iPhone?

[viperrepiv]

Hey All,

Sorry for posting two topics so close to one another, but this time I am trying to go from an unlocked 2G iphone running 2.x to the latest iphone version. I don't care if the jailbreak is lost, I just want to avoid it bricking the phone. I don't think any of the 3.x releases update the baseband, so I think I should be okay, but I don't really know if that hunch is accurate. Anyone know if this is possible?

They don't update the baseband for 2G iPhones.
