Out of the box, the iphone supports over the air downloads of music only from the itunes store. However, there is no limitation on where your music must come from which you put on your phone via syncing with itunes. So whether you download from amazon or bittorrent or usenet all these files can be synced onto the iphone.
having said that, can you download music from your phone and play it like android?
i hope my tone doesnt come off as rude, i was asking since i dont own an iphone.
You can only download using itunes unless you jailbreak the phone.
