According to a proposed new law that would go into effect Jan 1, 2006 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 a microphone for my cell phone. Having a friend in the cell phone business, I talked with him and was able to come up with an alternative, working through Office Depot. These kits are compatible with any mobile phone and one size fits all. I paid him $0.08 each because he bought in quantity. Then we tried it with Motorola, Sprint, Verizon and Nokia units and they worked perfectly. A photo is attached so scroll down & take a look and let me know if you want one. Also, forward this to anyone you know, who has a cell phone, and who may want one!
