Hi, I just bought a 4S on 5.0.1 on Craigslist. I saw sbsettings and 5.0.1 and just assumed all was well. Now, I find there is no cydia. I checked to see if it's hidden and it's just not there. Also, bitesms is there but no standard message app. I can deal with bite, but really need cydia. Any way to get it back?
