Even me on the same page.
I have iPhone 3GS with following details. New bootram, Modern firmware 06.15.00, current iOS 4.2.1, SHSH full blobs for 5.1.1
Murdo, as you mentioned could you please let me know if I can upgrade my iOS to 5.1.1 since SHSH blobs are available for 5.1.1? If I upgrade my iOS do i need to jailbreak and unlock my iPhone again? If i upgraded my iOS to 5.1.1 do i need to activate my iPhone again with AT&T SIM? If I found some issues once I upgraded to iOS 5.1.1 or 6, can i revert back to iOS 4.2.1(as I had partial blobs available for 4.2.1)?
