Ooma broke away from its tie-in to its own hardware on Tuesday through an iOS app, Ooma Mobile ($10, App Store). The app uses an existing Ooma account to make VoIP calls from an iPad, iPhone or iPod touch to real-world numbers, even over traditionally off-limits 3G. Although it doesn't use Ooma phones like the Telo, it still has the company's own voice compression technique and may help with 3G use by cutting down on bandwidth use.
