Exactly. I've seen this as well in both instances but haven't seen it on mobile phones. It's something so obscure that you're going to have to really want it to turn it on. I don't think the Port 25 example holds much water here.
Many/most GSM/GPRS/etc operators will have multiple APN's - one which is setup for NAT, and the other which gives a public IP address. By default, most "dumb" phones will use the former. Data cards will use the latter, and smartphones seem to be split between the two - although obviously it will vary between providers. Scott.
