Sorry to be starting a new thread on this, but I have not been able to find much about 4.3.4 I was given an old 3GS that is ATT and has never been unlocked or jailbroken. I do not have the SHSH blobs backed up neither, obviously .

I would like to unlock the phone because I live in Mexico. Any ideas or recommendations on the best way to do this considering I am on 4.3.4? Is their an option that I am not finding? Should I upgrade to ios5 and just wait for an unlock?

I have two additional unlocked phones down here (2G and 3G) so I have the basic skills to do it....I just need some guidance because I cannot find anything on 4.3.4, especially without the blobs.

Here is the details> 4.3.4 (8K2) firmware 05.16.02

thanks for the help in advance!
