"Google continues to make strides with its Nexus One smartphone. After revealing details to have a Nexus One version for Verizon and Vodafone, documents on FCC’s site suggest Google could be working on an AT&T version with full voice and data support over the carrier’s network.
FCC has approved a device from HTC, maker of the original Nexus One, with a model number 99110. The original Nexus One had model number 99100.
Soon after the word leaked about the possible AT&T Nexus One, the FCC pulled documents from its site. Speculation suggests that because Google and HTC aren’t saying anything, they might be in negotiations with AT&T to offer the device on a subsidy. If AT&T declines, Google may go ahead and offer the device online at the Nexus One Store and leave getting data service up to users."
If this is true then here's hoping that we can get a "true" world fone that will work in 3G on all three NZ carriers..
