I am still using my original 3GS. I buy a lot of music, some on my iPhone, some on my Mac. I hook up my phone and do transfers. Over the last few months, I started having problems maybe iOS related? While playing music, my phone gives me an error that it cannot download the song. Some of these songs have been on my phone for a while, they even have the artwork showing! The number of songs keeps getting larger. It's currently at 230 songs to download. It will not download any of them, just gives me an error. I can't even download them when I am wired to my Mac. Any thoughts? I want to hold off on a new phone until the new one this fall.
