2.2.1OTB iPhone 3G unlock question

I just bought one locked iphone 3G. It is originally with 2.2.1.

I searched the whole forum, It seems that I can only jailbreak for now, software unlock is not possible but hardware unlock is possible. I checked the blog and no post is mentioning the progress of software unlock of 2.2.1 OTB.

I am just wondering if there is a project working on new version of yellowsn0w that can deal with 2.2.1. If so, I'll be confidentally waiting for the solution. Thanks a lot.

Just keep checking the Dev-Team Blog
