NSN Tech implemented into iOS4.2.1 = good!

With its latest iPhone iOs 4.2 software, it looks like Apple is joining efforts to cut smartphone signalling down to size. Tests by Nokia Siemens Networks have shown that iPhone iOs 4.2 supports a technology called Network Controlled Fast Dormancy, which we have already introduced into our networks. Basically, the technology makes the network and the handset work together to create the best conditions for smartphones to work quickly, yet have a long battery life and minimize network congestion....

you don't shut down the radio, you just stop transmitting and sending signaling messages. You receive calls because your phone is "hearing" and networks send page messages.

The problem in congestion is originated because your iPhone is trying to close the transmission all the time (therefor saving battery) but that creates lots of signaling messages, through signaling channels that some networks (i.e. AT&T) can't handle properly. Every network has 2 capacities somehow: throughput and signaling. Either of them can collapse and drop your call/session.

NSN's networks have more capacity for dealing with this type of traffic. This is what was called "smartphones challenge" in networks, and was a big headache for a couple of years already. NSN is (arguably) the best handling smartphones, and iOS 4.2 brings an additional optimization of this functionality.

win-win! for the networks which support fast dormancy!
