I'm giving away my speaker for my iPhone 4s to my girlfriend. I was going to replace it with the same one, Logitech 715i, until I remembered it's a different connection for the iPhone 5. I plan on getting the new phone when it arrives. I assume the Logitech 715i won't be compatible with it, right? It's got the old connection. With that said and if so, any recommendations for a portable speaker for traveling? I really like the 715i -- I don't like too small. This one seemed the perfect size and has excellent audio. And it also charged the phone, another attribute I want. Thanks.
