Boingo Wireless yesterday announced that it's giving iPhone users free Wi-Fi throughout the month of August in 13 U.S. airports. The offer is obviously intended to get iPhone types hooked on Boingo - after which they'll have to pay.

The irony, of course, lies in the fact that AT&T, which is supplying the mobile connectivity for the iPhone, didn't think to do this on their own frickin' network...

"iPhone users are searching for Wi-Fi options that will keep the device's coolest features and content functioning at lightning speeds when on-the-go," says Boingo's Dawn Callahan. "With our extensive hot spot coverage, choosing Boingo is a no-brainer for iPhone users who are looking for public access options beyond EDGE. This free promotion is a great opportunity for iPhone users to see for themselves."

The list of airports is as follows:

AZO - Kalamazoo/Battle Creek International Airport

BNA - Nashville International Airport

BWI - Baltimore/Washington International Thurgood Marshall Airport

DTW - Detroit Metropolitan Wayne County Airport

EWR - Newark Liberty International Airport

JFK - John F. Kennedy International Airport

LGA - LaGuardia Airport

MDW - Midway International Airport

MSP - Minneapolis-St. Paul International Airport

OKC - Will Rogers World Airport
