When the full iPhone OS 3.0 will be released, how will we upgrade our jailbroken iPods? I mean, we can just restore to the new 3.0 stock FW, but then all the data is gone. Can we Shift+Upgrade firmware to jailbroken 3.0? (say there is a jailbreak already for 3.0) and not to lose all of our data? Can we restore and jailbreak to 3.0 then when first connecting to iTunes, there is "Set up a new iPod" Or "Restore from Backup" will we be able to restore from backup? I don't want to lose the apps saves and the settings, music and videos and the app itself we can re-sync with iTunes, but the saves and setting.. awrrr what shall we do?
