Question about preserving baseband for iphone 4

[rendersix]

So I posted this in a different forum, then realized it may be more applicable here... so reposting. Sorry for the multi-forum spam

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!

Stay at IOS 4 or if you want IOS 5 then restore to custom firmware of IOS 5 to preserve your IOS 4 baseband just to be on the safe side.
It is possible with this 04.10.xx bb, it can still be unlock with Gevey Sim but i am not 100% sure.
