I would say don't get the "iPhone Magic Package", instead make your own stuff.
With the new 2.0 software for the iPhone and iPod Touch you can take a screen shot by holding the power button and the home button down at the same time. You can then upload these images to your computer and manipulate them on an image editing program.
Here a couple I've made (low quality images here though) just to give you some ideas:
They're pretty easy to make and you can do some really cool stuff.
Here is a video by Kam Magic where he uses his iPhone in an ACR routine, which looks really good and is very effective.
I hope some of this stuff helps.
