Pogue’s latest post about Line2 seems too good to be true. A dollar app that gives your iPhone a full second number with voicemail, texting and all that. Even when it’s not running it rings to your regular phone number. If you’re in a wi-fi zone, it uses that instead of AT&T without using any minutes. You basically save 30-50 a month even after the 10 a month fee for Line2! Additionally, and amazingly (since the new iTouch/Pad have a mic) it turns your iTouch into a full functioning phone that will even take a voicemail (and email you about it) when you’re not wi-fi covered. Incredible.
