A few weeks ago when BIS 2.8 was rolled out we learned of a new feature that would sync contacts with Google. At the time it was believed that this feature wouldn't be enabled until the official release of OS 5.0. Good news seems to be that we were wrong. The feature seems to be showing up on BIS sites now. Though it looks to be only be enabled for Verizon and AT&T users. Never the less, you still need OS 5.0 to take advantage of this new option.
