Has anyone used iphonetrip.com in France and can you tell me which network it uses? I have an unlocked Huawei E585 (a "MiFi" type device for Americans) which is UMTS 2100 and UMTS900 so I am interested to know which network iphonetrip.com roams onto.

I plan to use the E585, along with a number of iPhones and an iPad.
