I have T-Mobile USA service and am wondering what the particulars are about sending pictures from a cameraphone are when roaming internationally. I currently have a Treo 600, which is a tri-band (GSM 1900 for North America, and GSM 900/1800 for worldwide).
In my travels to UK & France, I have not had a problem accessing T-Zones, sending pictures to email or "My Pictures" (222) or to my flickr.com picture account using my US T-Mo account.
