I work for verizon ( i know more about CDMA) so im not too fond with GSM stuff. But have you heard of " QUADBAND "? I think that would be the BEST ONE SO FAR for a TRULY World phone.
Does anyone know which GSM frequency is used around Europe?
I noticed there are 4 or 5 different frequencies. 800, 850, 900, 1800 and 1900.
Which ones are needed for a truly "World Phone"?
Thanks.
