Network-wide firewalled Incoming Connections?

Network-wide firewalled Incoming Connections?

Parent article: What lessons can be learned from the iPhone worms?

How many cellphone networks allow incoming connections? In South Africa I only know of one that does, but you have to sign paperwork acknowledging that you'll be changed for traffic that's wasn't initiated by you before you can get access to that APN.

Is this an oddity that isn't seen elsewhere?

It might be different if you're already inside the network. My understanding of one provider's 3G network is that it assigns everyone a 10.x.x.x private address, then has several layers of NAT to get to the outside world. That precludes any incoming connections from the internet, but it doesn't necessarily stop one device connecting to another internal to the 10.x.x.x network.

You could still have people reach you if your running a tunnel to a external
server.

But remember that the iPhone has Wifi capabilities and like most consumer
mobile devices it will probably happily latch itself to any network that
presents itself to the phone.
