I sent this comment to Sparkfun about their Bluetooth Mate Silver product.With a simple mod, this module facilitates uploading Arduino sketches via Bluetooth!There are two signals that you may want to consider bringing out to pads or possibly jumper options -- pin 33 (remote DTR), and pin 34 (remote RTS). I also set the module into the "MDM" mode with the "S~,3" command. thank you, Bill Welch, bvwelch 2-April-2011
