For all of you who have not seen this: http://www.sparkfun.com/commerce/product_info.php?products_id=7917
The manual is here: http://www.gm862.com/en/products/gsm-gprs.php?p_id=12&p_ac=show&p=7 You can build up a little phone with a gumstix and one of these. You can script with Python. Or you can use a beagleboard, and you have the option of plugging your phone into display/keyboard when you are home. It's the anti-iPhone, you own the whole thing, you can do what you want. Headphone/mic would not go via Plan 9, it is a direct connect. These really are little cell phones in a module. I worked with these several years ago at LANL. It was not so easy back then as the SIM support was not great in the US. I never got PPP working on it as you were supposed to be able to do. You have to be careful, too: I fried one, guess it was static sensitive? But note that they're even selling modules for use as controllers for your house!http://www.sparkfun.com/commerce/product_info.php?products_id=8700 Just an interesting project for someone. I think it would be easier now, I even see SIMs for sale in airports. ron
