Show HN: How to use a phone without a carrier contract

Hi HN. Our new app lets you make and receive calls on your own phone number anywhere in the world without paying roaming or long distance charges (over WiFi or 3G/LTE). Calls and texts to the US are $.01/min and we give you credit to get started. It also works for tablets, ipod touch and phones without a contract. The iOS version is available here: bit.ly/youroamios and Android is here: bit.ly/youroam We would love your feedback and suggestions emailed to hi@youroam.com or posted on HN.
