Good news, everyone! As you may have heard by now, the iPhone 3GS and 3G are now fully carrier-unlockable thanks to blacksn0w – but that’s not all!

In addition to making your iPhone carriers SIM card slot play friendly with just about any SIM you can cram in there, blacksn0w also undoes some of the locks put in place by Apple/AT&T during the upgrade to 3.1. Namely, it removes the IPCC lock which prevented tethering.

I just got my iPhone up and tethering in all of a few minutes – we’ll have a tutorial up in just a bit.
