In the on again, off again department ...

AT&T knows Wi-Fi is hot, and free Wi-Fi is even hotter. Which is why free AT&T Wi-Fi access is now available for Apple iPhone at thousands of hotspots nationwide, including Starbucks.

Now you can can relax and access music, email and web browsing services with your favorite brew in hand from the comfort of your nearest location. (That's if AT&T has a good signal in your area.)

AT&T provided a number of early hints that the service would be coming and sent a message to iPhone users announcing the plan. (And who paid for those bits of data?)

You can locate these free Wi-Fi hot spots through AT&T's little online tool at www.att.com/attwifi or can locate a Starbucks instead.
