IPad – the Headset icon on apps in dock on iPad

My experience is your best value is a USB based headset with over the ear cans and a plastic boom mic to get it near your mouth.

• Plantronics makes many
• Logitech does as well

For a price premium, you can get headsets that use the 1/8 inch headphone jack, but these overwhelmingly have microphones in the cord which makes for a noisy conversation in my experience. Again, the Apple touch interface for the microphone where there is a play/pause button as well as volume up/down seems to drive the price of many units higher (in the $80 to $140 range in the US). Your best bet is to look for made for iPhone models since they work best with the Macintosh sound in / headphone out (of course many off-brands work just fine, just be sure you understand the return policy if you can't shop from a store that can speak to your need for it to work with OS X on the Mac hardware.)

You might want to make sure your app is correctly associated (for that you can use the free RCDefaultApp panel).

If you fancy changing icons, you can try the arguably pricey Candybar from Panic inc. which is excellent if you love playing with your icons, but that's all it does, so for 6 Starbuck's Coffee Latte you can do that :p

Please note that if you change an icon, you will probably have to restart the finder (and/or the Dock) for the change to be reflected (Logoff also works).
