Hi folks . I purchased an iphone 4 s/hand and it has ios5 loaded on it now since i uploaded beta7 my songs will not play well the ones which i transfered from i tunes the ones which i purchased from i tunes store will play . Now after looking on the net i came across this * After updating to iOS 5 beta 7, your music may fail to play. If this happens, turn off iTunes Match in Settings > Music, and turn it back on. Now i dont have i tunes Match on my phone !!! Please excuse my ignorance as this is the first smart phone i have owned . Also my phone wont sync now as it comes up saying i need 10.5 and that what i have on my pc just wondered if my version 10.5 of i tunes has been superseeded and thats why the phone wont sync .
