theres an app called app backup you have to do research on it because my dad hacked mine iPod
no, first of all to go installous and go to the "downloads" tab. and just click it from there... if that doesn't work then try switching off your iPod touch. If that doesn't work then just get a "free" app from the app store and then re-download a different app from installous. Trust me i have done this before and it works. (but IF THAT doesnt work then...un-jailbreak your iPod touch/iPhone and re-jailbreaking it..) well those are all the things I've got. IF none of them don't work restore your iPod.
steal it
yes
Yes they do, any app that you want for free would have to be downloaded through installous. That is the only way to get them for free.
once restored, everything is gone!
it depends on how much space you have left its not much though you need to keep getting space
Try installous or cydia, not on appstore
I don't think so.
Technically yes because it will remove your jailbreak if you update and any cydia apps, such as installous will be deleted.
Every Thing!!! just Jailbrake and install Installous!!!
Go to installous, ang go to settings
Yes, all apps on installous are free. I have an ipod touch 4th generation 8gb and i downloaded intstallous on cydia (free) and every app o there was free. They had like every app too, including angry birds and the new angry birds space. Even the 999.99$ app IVIP BLACK!!!!! Amazing feature, you should definitely get it.
