How to wonderful without iTunes

I bought the part, because I want to shovel on my iPhone 4 without iTunes MP3s as possible.
And it works very well in combination with the associated app from Kingston.
I close normal-looking external hard drive (no extra power supply) or a USB stick to the card reader and then dress with the help of the Kingston app on iPhone MP3s or delete them there. The other direction (ie from the iPhone on an external storage device) also works.

Although one must then use the built-in App Player to make do and can not use the default player, but that suits me.

It is also handy that you can copy photos from iPhone to an external memory.

The only drawback in my opinion is that the app but often times "crashes". This also happens if you "just" listening to music with it. Therefore 1 star deduction. I hope the app will be stabilized.

Cool is that one on the App Photos
