I have an iPod Touch and a Macbook Pro, and my friends have iPhones. I chose Droid over iPhone because I love the fact that it's open source, and also the immense customization that's possible, even without root access. However, one advantage I see in both my Macbook and iPod is the different "profiles" for volume; when I unplug headphones from my computer or iPod, the volume changes to whatever I had the speaker volume set to. I was wondering if there was an app/tweak to do something similar with the Droid? Thanks
