hello every1
i updated my iphone 3g 8gb to v3.0 done the jailbreak and the ipod wouldnt work
tried restoring, re-setting etc but nothing worked
so i thought i'd write exactly what i did hoping it might help you,
first i downloaded the v3.0 software from iclarified and restored my phone using it,
when asked with the option set up as new iphone or restore from back up i selected set up as new i phone
then i synced the music and let a few tracks download from pc to the iphone i
then tried and checked to see if they showed and played and they did
then i used the redsnow jailbreak package to jailbreak the phone and the ipod was still working fine.
NOTE:after numerous tries of various methods the only different thing i tried which may have made the difference seems to be setting the phone up as a new i phone and syncing music before jailbreaking
hope that helps
YB
