22. Line2 iPhone App

Toktumi’s Line2 iPhone application brings VoIP to the iPhone or iPod touch, allowing calls over Wi-Fi or a 3G network. It’s ideal for those who want a second phone number for business or personal use. Line2 looks very similar to the iPhone’s native phone application and facilitates conference calls with up to 20 people. It also separates your contacts into business or personal groups so that it’s much easier to sort calls. Throw in visual voicemail, call screening, do not disturb hours, and even an automated attendant, and you have a viable, money-saving alternative to a home or business landline.

99 cents (app), $14.99 per month(service); www.line2.com
