iPhone tethering application up, down, up, down: The NetShare connection-sharing application from NullRiver has made a couple of appearances on Apple’s App Store, the only authorized place from which owners of iPod touch and iPhone devices can purchase software for uncracked equipment. NetShare appears to violate the terms of service for AT&T, although this wouldn’t be the case with all carriers worldwide, by bridging 2.5G and 3G network traffic via the Wi-Fi connection on the iPhone. A laptop or desktop needs special configuration to connect to the iPhone, but various reports show it works fine. AT&T offers tethering with other smartphones - but not the iPhone - for typically about $20 more per month, comparable to a national hotspot aggregated subscription.
Speaking of AT&T, they like WiMax as a wire alternative: AT&T is bullish on WiMax, but the fixed kind used to replace wires in places they have no cable.
