And what happens when you are walking by (but not in) the coffee shop with the free WiFi and get arrested just like the poor man checking his email in his car?

By DAVID POGUE Man, oh man. How'd you like to have been a PR person making a cellphone announcement last week, just as the iPhone storm struck? You'd have had all the impact of a gnat in a hurricane.

But hard to believe though it may be, T-Mobile did make an announcement last week. And even harder to believe, its new product may be as game-changing as Apple's.

It's called T-Mobile HotSpot @Home, and it's absolutely ingenious. It could save you hundreds or thousands of dollars a year, and yet enrich T-Mobile at the same time. In the cellphone world, win-win plays like that are extremely rare.

Here's the basic idea. If you're willing to pay $10 a month on top of a regular T-Mobile voice plan, you get a special cellphone. When you're out and about, it works like any other phone; calls eat up your monthly minutes as usual.

But when it's in a Wi-Fi wireless Internet hot spot, this phone offers a huge bargain: all your calls are free. You use it and dial it the same as always - you still get call hold, caller ID, three-way calling and all the other features - but now your voice is carried by the Internet rather than the cellular airwaves.
