There was reason to suspect it but so it deserves to be clear! The future unlocking tool, PwnageTool 2.0, developed by Dev team, will not be able to dsimlocker iPhone 3G (unlock the phone part) first. The Dev team is relentless currently to find a solution override the new baseband.
As a reminder, the Dev Team however succeeded a few days ago, get out of prison (jailbreak) the iPhone 3G, supports it.
PwnageTool 2.0 should however allow accessApp store and above all, being able to finally free totally the firmware 2.0 on first generation iPhones!
We discuss it on the forum.
