Nexus One is now ready for AT&T, Rogers Wireless 3G networks

For anyone interested in purchasing the unlocked version of the Nexus One, your options just increased.

Google has announced that unlocked Nexus One smartphones will now be compatible with the 3G networks of AT&T in the U.S. and Rogers Wireless in Canada.

The SIM cards used in the locked version of the Nexus One are 3G-enabled, but they aren't compatible with all frequencies. Thus, on AT&T, they're only compatible with 2G or EDGE networks.

We've been waiting some time for a Nexus One/AT&T announcement of some kind. There have been rumors here and there, notably a brief appearance of the smartphone with a contract on Walmart's website. And then there are the stories about this HTC phone with other carriers, like Verizon Wireless potentially later this month.

But remember that the unlocked version of the Google smartphone costs $529 a pop, but that is the high price of wireless provider freedom.
