Most all phone plans I've ever seen would incur significantly higher costs to use out of band signaling as opposed to sending a TCP keep alive (which can be <100byte) to the server every now and then... Doubly so for the lucky guys with flatrate GPRS. > My whole point is that maintaining a persistent connection between the > mobile phone is (in my opinion) not efficient, not as easy, and more > prone to error than using some sort of out-of-band notification. It could depend on the plan you have and the frequency you get mail, but at 0.10E per SMS, I rather send a few bytes over GPRS every now and then than a SMS each time you get mail. _______________________________________________ OpenMoko community mailing list community@lists.openmoko.org https://lists.openmoko.org/mailman/listinfo/community
