I have the iPhone 4 and just upgraded from 4.3.5 to 5.0.1 using redsn0w. I preserved my baseband of 4.10.01 and must keep it this way for the unlock to work. After upgrading from a previous 4.3.5 jailbreak, I went through the steps to set up my iphone and found that cydia was not loaded on my iphone. Is there a way to load cydia to my iphone without having to rejailbreak it?

Any advice is appreciated. Thank you
