Very interesting...there is no flat-rate mobile service available
here in Italy... There used to be some launch offers for
GPRS but now you pay a lot fro every kbyte you
download and upload.
Anyway should be interesting differentiating the traffic also
by guaranteed QOS. Like described in this Symbian press:
ultiple PDP contexts allow users of mobile
phones based on Symbian OS v.7.0s to access
more than one network service at the same time
and with varying QoS. Users can access email
whilst simultaneously surfing the web or
downloading an application. For network operators,
this allows multiple, simultaneous revenue
streams from a single handset, each with a different
QoS and each with a different charging model.
