Ok, so... I know there is no unlock yet for iphones on the baseband 04.10.01, which is what mine is on.

My question is: if I do an apple upgrade to iOS 5, is that going to upgrade the baseband? Does it matter if it upgrades the baseband at this point? Should I wait until there is downloadable restore file (to my knowledge it's not ready yet for windows...)

I just learned about preserving the baseband recently... so I was just curious how it is working with iOS 5.

Thank you!
