Hi All,
I have two questions.
First, can I jailbreak my jailbroken iphone again, if I get my ios 4 crashed and I wasn't able to use internet. I am concerned about camping.

Second, if so, can I also perform carrier unlock with Ultrsn0w without internet?

Presumption : Custom Ios 4 is on my laptop.

If so, where can I safely download Jailbreakme and Untrasn0w??

IOS 4 jailbreaking is my first experience and I never falls in love with my iphone and ipod until I jailbreak them. Using Ipod would be so boring for me without jailbreaking.
