I used jailbreakme.com to jailbreak my iPad fw.3.2.1. It now looks like everything is ok. I can see Cydia but when I try to install app in Cydia, I'll see the error message "The requested modifications cannot be applied due to required dependencies or conflicts that cannot be automatically found or fixed"
Also, I tried to install crack app downloaded from internet through iTunes, and it cannot be sync into the iPad. Can anyone help what happened? :(
