An anonymous reader writes "Google Voice is now open to anyone in the US, removing the need to search for an invite. At the Google Voice site, anyone with a US IP address and a US phone number can sign up for an account. Non-US IPs are blocked, and non-US-based phone numbers are prevented from attaching to Google Voice (with the single odd exception of the 403 area code of southern Alberta)."
Good timing on the part of Frontier Communications Corp., which just filed a lawsuit
claiming that the Google Voice feature connecting a user's home, work, and cell phone numbers to another number infringes one of their patents.
