I have an iphone oob 1.1.2 After following the STEP 1 - DOWNGRADE YOUR 1.1.2 OTB to 1.1.1
on STEP 2 - JAILBREAK and ACTIVATION I begen the download of jailbreakme.com. but it stops on downloading 89% and cant move any more.
¿what should I do?

Usually this is because there is a problem on the server, or maybe your internet connection. Wait some time (a few minutes if you are impatient, or a few hour if you want to be sure) and try again.

try using http://www.jailbreakme.com instead of http://jailbreakme.com.

Turn your phone off and back on before trying again, remove any security from your wifi network.

If all that fails use CARNAVAL, works great

Thank you,
I have tried a few times to reconect but it still shows downloading 89% and my wifi works . What means using Carnaval ? should I beguin all the process again ?
Thanks ..
