Hi I got this problem after I JB my 1.1.4 ipod. The first time I JB it I cannot play any song. Although I can see the song list and scroll through it but when select any song it just dun play. Then I restore it and JB it again this time can play song everything is normal for half a day then same symptoms again. Anyone experience it before? Or anyone can enlighten me on the problem? I use the ziphone 2.6 to JB.
