Iphone 4, IOS 6.1, BaseBand (04.12.05) Jailbreak is done with snowbreeze, followed the steps mentioned, but still seeing the message "No Service". Should I start over again with Redsnow or evasion? Can anybody please confirm


I have ios 6.1 and baseband 4.12.05, I have cydia on my phone but I downloaded it through evaisi0n. I followed these steps and downloaded the ultrasn0w fixer for ios 6.1 then downloaded ultrasn0w but i still cant use other networks

that baseband isnt supported yet, supposedly.

iphone4 iOs 6.1

Ultrasn0w is probably not in a position to handle the problem with the baseband 04.12.05,
that´s upsetting !!


Plz I have an iPhone 4 6.1 BB 4.12.05, plz help me, thanks !!


For bb 04.12.05 there's a sim called superior sim+ it's meant to unlock it I've seen it online for 28 dollars just haven't tried it yet
