You want to buy the BOSE-Hifi, did I get this right?
Well, there's a problem with, the Lighting to 30 Pin connector adapter doesn't exist! So I would recommend you this product: http://store.apple.com/us/product/H9851VC/A/bose-soundlink-bluetooth-mobile-spea ker-iinylon-edition?fnode=4b
It is with Bluetooth and you can use it with your iPhone 5 and your iPod Touch 3rd Generation!
Hope I solved your question
