Downloading iPhone music is a relatively easy affair: choose your source, click on the download button, and put it on your iPhone. Nine times out of ten this works just fine. Depending on where you download the music from, however, the iPhone might not be in the correct format. When this happens your iPhone will struggle to play the music (or movies).
Fortunately this is really easy to solve: there are free software applications provided by many of the main providers of iPhone music that will allow you to convert the music (and video) files into a format that is entirely compatible with your iPhone. Getting iPhone music onto your phone has never been easier.
Some of the services even offer from DVD conversion software that puts your DVDs into a format that can be read and enjoyed on your iPhone.
Some of the download services that allow downloads of iPhone music vary in speed of allowed download: if you sign up to one of these services then your first priority should be to ensure that you’re not signing up to some 56k service that will take three weeks to download your music. Remember that your connection is likely not the bottleneck, but the remote server will be.
