According to a proposed new law that would go into effect January 1, 2008, you will no longer be able to use a cell phone while driving unless you have a "hands free" adapter. I went to Circuit City and they wanted $50 for a headset with microphone for my cell phone. Having a friend in the cell phone business I talked to him and was able to come up with an alternative at Office Depot.
These adapter kits are compatible with any mobile phone and one size fits all. I paid 8 cents apiece for them. We tried them with Motorola, Sprint, Verizon, and Nokia units and they worked perfectly. Take a look at the photo below and let me know if you'd like one too. Your friends may want to know about this, so forward it to them as well. Maybe if we buy in bulk we can get them even cheaper!

I can hear you laughing!!!
It does look funny and you'd have a job attaching it while driving!
We've had that law in NSW, Australia for quite a few years!
