iPod touch iPod touch playing up after jailbreak

After ages of trying to figure it out, I finally managed to jailbreak my iPod touch on 4.3.5... I did this with the sole intention of getting pokemon. Since I jailbroke it, I have managed to install gpsphone. When I tried to install the gba roms however, they would not download. I did this from apt.123locker. O then decided to try using installous to find some. Once it downloaded, everything seemed to go perfectly, but installous isn't showing up on the iPod. Since the jailbreak from 4.3.5, I have lost access to the settings, so I can't even turn off my wifi, or change brightness(I do that a lot)
I eventually got sick of it, so decided to try and just restore the iPod, but iTunes can't even find my iPod to give it the option to restore.
Can anyone help! It seems almost everything possible has gone wrong. Is the a Cydia app that will give me back the settings? And how can I get installous? Or the pokemon roms, the sole reason I jailbroke the thing in the first place. I don't want to have to restore it, but if I have to, how can I do that?
Thanks for reading this far, I really hope someone can help

the problem with restoring it, which i believe i will have to do, since i'm not getting much out of the jailbreak anyway, is that iTunes doesn't even register that i have it plugged into the computer. I'm trying a few things now, but i'm not sure anything will work.

Unfortunately we aren't really supposed to help with installous since it's piracy and downloading paid apps for free is illegal. I suggest paying for your apps.

When I first wanted to jailbreak the thing, I didn't even know that you could do that. I was just following instrtuctions from a frriend to get pokemon... the whole stupid reason I got into this mess
