If you have the 5.08 bootloader, you can roll back the baseband to 2.28.0, which
is unlockable.
I downgraded from 3.0 beta 5 to 2.2.1, then rolled the baseband back to 2.28.0.
BTW - you look nothing like my son...

How can I tell if my 3G has the 5.08 bootloader? I bought it this past November, but had it replaced a couple months ago and am running 2.2.1. Something tells me I am screwed.
If it is, how do I roll the baseband back to 2.28.0 (is that considered the unlock?)
