Jailbreaking, unlocking or downgrading possible?

Was searching through settings and figured out I should just turn off auto brightness yes that fixes it.
I get 2-3 signal bars, but suppose that's because I'm in apartment.
Installed SBSettings and SBRotator but only have SBRotator settings under Settings... Weird don't don't know where to access SBSettings..

I kind of miss some Android features but damn this is hot

Slide your finger from left to right at the top of your screen to access sbsettings.

Ah ok thanks, i saw my friend has that when he slides top and i was wondering how i do not when i first got the phone xD
Now I'm having problems with appstore.. Can't register without billing, I googled and it said you just need to select "none" as payment card, and I can't select that... Also read you can activate account through iTunes but when I click download and login I get "unknown error occurred 9808 We could not complete your iTunes Store request. There was an error in the iTunes Store."

EDIT: Ok a friend gave me his AppleID... But now that I can download, Pocket Legends disappeared from Appstore :S.. Though i can still see it on iTunes :/.. Is it me?
