Hey Guyz, recently i happened to see many cool ios 6 apps and cydia tweaks.. As i am using my Jailbroken Iphone 4s ios 5.1.1, I couldnt install some apps and tweaks which are compatible with ios 6. I really liked some of the cydia tweaks and i want them on my 4s... SO i just wanna ask u guyz that, how can i upgrade my ios 5.1.1 to ios 6 or is there any way which helps me to run applications and cydia tweeks of ios 6 on my ios 5.1.1
