A new app is out that allows you to copy your iTunes collection to your BlackBerry PlayBook. This is a nice easy way to get all of your songs from iTunes to your PlayBook. Currently it does not support copying music from your PlayBook to your PC. The cost is a deal at $0.99.

Software description from the vendor:

If you're like me, keeping your mobile devices up-to-date with your latest music purchases is a hassle. I've always wished it was a simple as pressing a button -- and now it is. iTunes Sync allows you to copy your iTunes collection from your Windows PC to your BlackBerry® PlayBook™ with the press of a button, no wires, no hassle.

Download a new song on your PC? No problem, just open iTunes Sync on your BlackBerry® PlayBook™ and press 'Sync', and that track will be copied onto your BlackBerry® PlayBook™ wirelessly in seconds.Download all of your music, or use features that allow you greater control over what music gets copied to your BlackBerry® PlayBook™.
