How do I pair my Jawbone with the iPhone 4 / iOS4?
If you find yourself wondering why your Jawbone won't pair with your new iPhone 4, or are having problems pairing your Jawbone with your 3GS that you recently upgraded to iOS4, you're not alone.
Here are instructions from Jawbone that are helping most people get paired up again:
1. Start with the headset OFF (slide the power switch to OFF, the position where you cannot see the blue indicator).
2. Press and hold the TALK button
3. Slide the power switch ON.
4. Wait for LED starts to flash red and white.
5. Release the TALK button.
The headset is now in discovery or pairing mode. On your iPhone, go to the Bluetooth settings and search for (or add) Bluetooth devices. When found, select Jawbone ICON. When prompted for a passkey, enter 0000.
