hi guys, i have bought the 3.0 firmware update for Ipod Touch 2G. Now if i am to use Itunes 8.2 to upgrade to 3.0 from 2.2.1 jailbroken and then use redsnow to jailbreak 3.0 will i lose any of my data? is this recommended? or will cydia be messed up due to apps already installed? i just do not want to lose my apps. if not what is the best way to do this.
