The Dev Team has released their 3G unlock today, and it’s available to people on the 2.28 baseband (firmware 2.2).
The unlock works exclusively with baseband 02.28.00. This baseband is provided by the latest firmware update (2.2) from Apple. Youâ€™ll need to upgrade to this release using iTunes and then use QuickPwn to activate etc. There are plenty of tutorials about this on iclarified, bigboss, and other established tutorial sites. Because it works on 02.28.00, it is available to everyone on the planet. This means we donâ€™t need to unnecessarily expose holes in earlier basebands, which is an important concern.
Information on where to get this unlock and other important bits of information can be found on there blog here.
