Popular VOIP and telephony app Line2 has released a Line2 HD version for the iPad that lets users make or receive calls as well as text-message using Wi-Fi or 3G. The app requires an existing Line2 account (due to App Store restrictions, users must get the account from the website rather than within the app) and allows users to port over existing phone numbers, supports Visual Voicemail and generally turns the iPad into a full-fledged mobile phone.
