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.

When Indian police investigating bomb blasts which killed 42 people traced an email claiming responsibility to a Mumbai apartment, they ordered an immediate raid.

But at the address, rather than seizing militants from the Islamist group which said it carried out the attack, they found a group of puzzled American expats.

In a cautionary tale for those still lax with their wireless internet security, police believe the email about the explosions on Saturday in the west Indian city of Ahmedabad was sent after someone hijacked the network belonging to one of the Americans, 48-year-old Kenneth Haywood.

Of course, the terrorists could have sent the e-mail from anywhere. But life is easier if the police don't raid your apartment.

EDITED TO ADD (8/1): My wireless network is still open. But, honestly, the terrorists are more likely to use the open network at the coffee shop up the street and around the corner.

• Conduct periodic risk assessments to determine changes in the operations risk profile and assess control performance.

Belkin gives us plenty of time to get ready for streaming high def: FlyWire uses an adapted form of Wi-Fi in the 5 GHz band to stream HD without having the HD set in close proximity. They're not shipping until October, which could give you some time to get used to the price tag. A $1,000 model is designed to cover a home, and has various infrared and wireless options to control current A/V gear, some of which might be hidden in cabinets away from view. A cheaper $700 option covers just one room, Belkin says, and excludes the IR help. The transmitter has 3 HDMI jacks, including DVI support with audio inputs, along with two component and one composite video and audio input panels. The receiver has a single HDMI output. All HD resolutions are supported. These devices are aimed at people who buy large HDTVs and want to wall mount them.
