""""""in America giro diverse città:
dovrei andare a chicago, memphis, milwakee (si scrive così?), poi non so...
Quanto potrei risparmiare secondo voi comprando un cellulare o un palmare?"""""""
Milwaukee of the State of Wisconsin?
Chicago, Illinois?
Memphis, Tennessee?
Come to Dallas, Texas! E' molto piu' bello!
As for the cellular phone compatibility with the GSM system used in Europe, in the United States is not very popular and it uses the 1900 MHz band instead of the 800/1800 MHz band used in Italy. Here the TDMA and CDMA systems are the mostly used systems.
You can buy a Tri-Band GSM 800/180/1900 MHz like the:
Motorola V66 Triband GSM World Phone (Unlocked) for only $129!
