Hi guys, I'm looking forword to jailbreak by ipod touch 2g (2.2.1), but I have a few questions before doing so: 1. Are there any risks? (if so, what are the chances?) 2. Will I be able to upgrade to iphone os 3.0? 3. Will my ipod appear as a mass storage device (SD card or USB drive) ? (if not, are there any apps that can do so?) 4. Are the apps on Cydia and Installer free? (if not, can I download free ones via torrents?) Thanks !
