(adsbygoogle = window.adsbygoogle || []).push({}); I have one ps3 in my house and it is on 3.50 and i have bought my jailbreak and downgrader, if i downgrade to 3.41 and jailbreak then put on my custom patches can i then backup all my shiz and upgrade to 3.50 and then use my backed up stuff will i still be able to use the custom patch that i installed?

Yes. But you wont be able to change the patches. and there is no reason for backing up, unless i missed something?

You lose all on your hdd when you jailbreak or something dont you?
and if i to what i said i was going to do will i still be able to use the dns thing to play online?
