i know that you can change the wifi bars at the top of the ipod touch. i know how to ssh my ipod and all that stuff (im not a newbie at this stuff). for a while now ive been trying to change the wifi signal bars and ive read many tutorials and my signal bars still wont change. ive put it all in the right folder in the themes. do i have to overwrite the airport files in the root? can anyone give me a good tutorial that explains everything?
