AT&T has been forging partnerships that give its roaming customers free WiFi while abroad, and it just struck one of the more logical networking deals that we've seen to date, if also the most lopsided. A pact with Boingo will let AT&T subscribers have 1GB of free data each month on Boingo's airport hotspots -- but, as with previous arrangements, only if they're subscribed to AT&T's $60 or $120 international data plans. Boingo subscribers, meanwhile, get a much better deal. They can use AT&T hotspots anywhere in the US as part of their existing rate, which could see them paying as little as $10 per month. Either arrangement will keep us online during a layover, and for that we're thankful -- but there's only one that's likely to have us pulling out our credit cards.
