prvi put vidim nesto ovako ali evo malo pretrage...
Code:
WRT54G-TM
The WRT54G-TM (TM stands for T-Mobile) is
also called the T-Mobile "Hotspot@Home" service.
It allows calls to be made via T-Mobile's GSM network
or via WiFi Unlicensed Mobile Access (UMA),
using the same telephone and phone number
(a special dual-mode phone designed for the service is required i.e. Blackberry Pearl 8120).
Additionally, once a call is in progress,
one may transition from WiFi to GSM (and vice versa) seamlessly,
as WiFi signal comes and goes, such as when entering or exiting a home or business.
A special router is not needed to use the service,
but the T-Mobile branded routers are supposed to enhance the telephone's battery life.

u svakom slucaju skroz nepotreban dodatak bar za nase krajeve.
