I'm currently using an iPhone 4 for everyday use and I'm using my old 3GS just for music as an iPod. I ordered and iPhone 5 and it should be here on Friday. My question is if you think it would be worth it to upgrade my iPhone 4 to iOS 6 when it is released even though my 4 will be used as an iPod after I get my 5? Is it a good idea to keep an iPhone with Google maps on it? I can't see myself using any iOS 6 specific features on my 4 when I only use it for music but I do like the new look of the app store. If anyone else is going to use an old iPhone as an iPod, feel free to share your thoughts.
