Loopt [Free - iTunes link], which matches social networks with location-based services into one smoldering hot Web 2.0 sammich, has struck a deal with AT&T that will let them update their iPhone users' location information even when the Loopt app proper isn't running.

Yes, you read that correctly -- the Loopt iPhone app isn't being granted any extra special background multi-tasking sanction by Apple for the iPhone, this is strictly a server-to-server, Loopt-to-AT&T deal, and it will come at a price. BusinessInsider scores the scoop:

Loopt will first offer the new always-on service in a trial for 5,000 users. You can sign up at Loopt's site using your iPhone's MobileSafari browser. After the 14-day trial, the always-on feature will cost $3.99 per month, added to your AT&T bill.

BusinessInsider also renews that old rumor about how Apple is seriously considering limited multi-tasking in a future software update. And, yes, they'll have to have something interesting to tempt users with in iPhone 4.0/4G next summer, so why not run with that? We'd like it!
