I have one of those knock off ipod touches, id post a name of it but i have no clue what it is. Its not on it anywhere. Either way. I was wondering if there are any boot screens and themes that i could download for it .. the ones that are on it now suck. They look cheap and they to me are not fuctional.

Thanks!

You need a backup firmware you know works safely to do this, these are never supplied with these players.
If you use a firmware from a different player you will BRICK it for sure and these players are nearly inpossible to recover, sorry.
