So...

If I'm a american guy and i have a ppc4100...ok...but...i' m going to Italy or another country with 900mhz band...i can't use my TRIBAND phone....

WHY???????????

where's my triband function???

it's not correct for me....

In Europe, u can use yr phone only in 1800Mhz. I dont know about Italy networks but for France, there are 03 networks, 01 is using 1800Mhs band full coverage, the 02 others are using 900Mhz for national coverage and 1800Mhz in big cities to be able to accept more communications. Ciao Ciao
