I have had an iPhone 4 for just about two weeks now, straight away i came across a problem with it, Firstly i had an ipod touch so i just synced it so i had all my music on the phone, all of my purchases worked fine but the CD's that i had burned into iTunes were not playing on the device, Then i found that When i went onto iTunes on the device it will not play the sample sounds for songs out of the earphones or the speakers. Then to make things worse i went on the YouTube app and the vidoes play perfectly just without any sound at all, i treid many vidoes without any success. So i contacted Apple and over the last couple of days they have been getting me to do various restores and nothing, so they want me to make a whole new account and to restore as new, which i dont think will work but will try it. before anyone asks i can play my purchsed songs through my device fine, they play out of the earphones and the speakers, even if i go on iplayer the sound works, this is wierd that some doesnt work and some does, Does anyone have any idea what is happening. Also when playing songs in a playlist the songs work fine, but if i were to click on a song i like missed the first few soconds, real wierd, any help will be appreciated.
