Yesterday Verizon started a new promotion to allow free Skype-to-Skype calling on its Smartphones, sending and receiving. On Android, this is possible with the new and improved Skype Mobile App. Verizon actually enables this through its voice network rather than over the datafeed, allowing good integration with Bluetooth devices and much higher fidelity of communication. Skype is a closed source, proprietary P2P voice protocol and unless that changes, it is probably a dead-end company. However, with sponsorship and special privilege from large telecoms, Skype perhaps has a new lease on life against the coming existential threat from the refactoring of Gizmo5 with Google Voice. In conclusion, if you have a Verizon smartphone or communicate regularly with someone who has a Verizon smartphone, consider using Skype.
