connections (network service), such as
GPRS in the GSM network. When you use
your device in GSM and 3G networks,
multiple data connections can be active
at the same time, and access points can
share a data connection. In the 3G
network, data connections remain
active during voice calls.
You can also use a WLAN data
connection. Only one connection in one
wireless LAN can be active at a time, but
several applications can use the same
internet access point.
