David Pogue at the New York Times (he’s my hero) posts about a service from T-Mobile that offers actual and he says, accurate, coverage maps of its cellular service.

You get “street level” isopleth (so nice to use that word again!) maps based on keying in a ZIP Code on the front page. Once in the app you can use an address or intersection to get at specific locations. I can’t tell what the mapping tool is beneath the app. Can you?

Carriers are always cagey about coverage, not wanting to let competitors know their secret “holes.” I stand with Pogue; they all should do this. And, what’s more, make the data mashupable so one can truly find the best service for their needs.

Wi-Fi Network News explains that Google may not get the patents for which it recently applied because other companies, notably Wayport, may already have patents that cover the same ground. The Google patent, which I mentioned here last week, speaks to the delivery of ads based on location and other properties of a wireless hotspot. That’s pretty close to two patents held by Wayport. The current CEO would not reveal the company plans, but did say the company is in talks with some big players about it patents.

Reader Duane tipped me off the Register article that has a beautiful illustration of how Google Earth has the prime meridian about 100 meters off its true location, bisecting the Greenwich Observatory.

Computer Weekly reports that an error in a McAffee virus program may have caused the inadvertant deletion or quarantining of files from several companies, among them MapInfo.

The error in anti-virus signature updates caused files on servers and desktops bringing down many corporate and university users. Other affected applications were from Oracle, Microsoft and Adobe.
