Ah, that is good to know I live in Germany now, and am always concerned in general about compatibility between US & European software - but if they keep the final release Non Downgradeable, that is a real worry if there is any conflict! I have the 1.21EU Firmware right now, and am really happy with its stability dealing with Macs, an XP PC, wireless Canon MP600R and windows mobile phones all connected at once, and would hate to lose that and not be able to Flash back to 1.21 from 1.3 if there was a problem!
