I have Unlocked/Jailbroken it via Limera1n and Cydia.
But, if i insert a sim, all i get is 'Different Sim Detected, Please connect to Itunes' - Emergency calls only screen.
I also tried replacing the Lockdown folder, and got past Diff Sim Detected, connect to Itunes business, but i had No Service what-so-ever. . Obviously that didnt work.
So back to being stuck on the Emergency calls screen, with Diff Sim Detected.
Anyone know how to Hacktivate it? Im going insane here.

Have you installed Ultrasn0w yet and also add this repo to cydia : cydia.pushfix.info , and install carrier reset fix. You might have to take your sim out and put it back on to activate you unofficial carrier.
I suggest you update to 4.0 like I did when they unlocked 5.12.01 and 5.13.04 then if u want better performance save your SHSH files and make a custom 4.1 IPSW with the SHSH and update preserving baseband. Jailbreak using limera1n or greenpois0n. Unlock using ultrasn0w. And you are done. If you don't want 4.1 or 4.0 jailbreak using redsn0w 0.95 b2,b3 or b5. Your jailbreak is likely to be the problem if not. You can try this right now...download Ultrasn0w 0.93 on your iPhone by using a downloads app and install through ifile. Search ultrasn0w0.93.deb
