A small example to get you started. It doesn't have to be a tip. It can be something that you wondered about our found out but isn't specifically about our phone. You can talk about other things too as long as it doesn't go against the forum's rules.
I have a Sony MW600 Bluetooth adapter. It's like a USB stick but it's a Bluetooth device you can plug headphones into and the device can basically control the phone. I use it with a stereo patch cable going into my car radio's input jack on the front of it. I use it for music and podcasts while driving. I will sometimes keep the phone locked away and charging while playing music. Sometimes I need the phone when I get out of the car. Everyone knows that if you walk away from something Bluetooth, if you get far enough, it will disconnect. When you go back to the car, it won't automatically reconnect. I had the phone in my pocket when I went back to the car. I don't know what made me not do my normal process of reconnecting the Bluetooth device when I got back to the car. I pushed the play button on the BT device, I previously paused the music with the same device, just to see what would happen. The BT beeped unusually, showed a different graphic on the screen, then paired with the handset and started playing music. Some probably know this already but I stumbled across it purely by accident. Now I don't have to go through the BT menu on the phone and reconnect to the dongle every time I get out if the car and return. I don't know how this would work with other devices. Just thought I'd throw this out there.
