Here is a strange bug I have, Apple still has not worked it out,
When I play songs on my iPhone 3G, some songs play with sound and some song play with not sound, yes they play, with not sound.
After lots of hours on the phone with apple, an exchange for a new iPhone, I still have the same problem, Fairplay version 2 files purchased from iTunes does not play on my iPhone, Currently Apple has escalated the bug up line to some Engineering department.
Thing have tried to resolve issue.
1 restore phone
2 rebuild itunes library
3 redownload files form itunes under a different user
4 load sound files from other computers on a clean restored phone
now fairplay version 1 play fine.
latest update for iTunes (version 8.2(23) fix the problem
