The Sony-Ericsson press announcement for the K850i is already back from July 2007 but contains a revolutionary piece of information most haven’t yet noticed:
"[…] The Sony Ericsson K850 Cyber-shot™ phone is a Tri-Band HSDPA and Quad-Band GPRS/EDGE phone […]"
Tri-Band HSDPA! This is great news since most current HSDPA phones are either only usable in the 2100 MHz band in Europe and Asia or in the 1900 MHz band in the U.S. Few if any 850 MHz mobile phones (e.g. for Australia and the U.S.) have yet been spotted. These two phones will change the game. One model produced for all parts of the world.
It’s not only great for economies of scale but also for users as it allows global High Speed Internet roaming, which is not possible today with single band HSDPA phones. People coming to Europe will be able to use their phones for high speed Internet access with prepaid SIM cards for Internet access which are available in many countries. Still waiting for the first brave operator in the U.S. doing the same thing.
P.S.: I know HSDPA data cards are also dual or tripple band today but I dream of a single device doing everything for me (and that’s certainly not a data card).
