Toktumi’s Line2 iOS app for the iPhone, iPod Touch and iPad — is a dual-mode calling app that uses either Wi-Fi or cellular networks — which gives iPhone users a second line, transforms the iPod Touch and iPad into calling devices and provides unlimited calls and texts in the US and Canada. And people are certainly taking advantage of the new all-you-can-text function, with Line2 users sending more than 1 million messages in the first four days after the updated app launched.
It also brings calling and SMS capability to the iPod Touch and iPad, so you can act like you have an iPhone whenever a wireless network is handy.
You may not be able to exercise your cell phone in the air, but a number of airlines now offer paid Wi-Fi on flights. Knowing that Line2 works for calling over Wi-Fi means users could theoretically yap away through the entire flight.
