Hi there! I have a iPod touch 2g MB model that's on 3.1.2. Is there any way I can upgrade to 4.0 and jailbreak it? Also, will my applications/cydia apps be gone? It's my first time upgrading so i'm not very sure of the procedure. I heard theres an updated redsn0w for my iPT but will it work on the final 4.0 version released today as the site says it'll only work on the developer's version. Thanks a whole bunch!
