The biggest complaint about the Nexus One at launch was the lack of customer support from Google. Google has been known for their online-only ways. When customers have problems with their products, Google typically uses email support and online forums to rectify the situation (unless you're a paying Google Apps customer).
With the launch of the Nexus One about a month ago, Google has seen the need to change its ways. Now seen on their Contacting Support page, Google has set up a phone hotline for Nexus One support. The number is 1-888-48-NEXUS and it will be open every day from 7:00 AM EST to 10:00 PM EST. However, it seems that Google's phone support is only available for order status and shipping issues. For technical support, repairs, and returns, users will need to call HTC's customer care. For service issues, users will have to call T-Mobile.
Being that Google was openly searching for someone to manage a phone support team, we knew it was only a matter of time before the number went live. While it's true, the phone support isn't all encompassing, it still seems to be a step in the right direction.
