I figured out how to send logos to phones (current have the Ferrari logo on mine) in the US. You have to have SMS service enabled. once you do, go to
www.wildsms.com and download their little program and register. it will give you 3 free messages (you have to give them a valid email address so you can enter the code). Select picture message and then browse image, and select the bmp or jpg file of you choice (in this case the M5 logo image). Once you do that, be sure to click on Operator Logo and then select your provider and type in your phone number. Within 3-5 seconds you'll have the message waiting on you phone and voila.
You can also "re-register" with another email address if you ahve one.
