Hey guys: I got some tips for those of you that are a existing Tmo customer and are at the end of contract; and Google wouldn't let you upgrade for $179. Here's what you do: First of all, if you are currently on a family plan, you have to call Tmo and have them split the account to individual accounts. Go to Google site and order the Nexus One selecting the $179 option to add a new line to your existing account . Put in your existing number so they can load up your information and process the order. Once you receive your Nexus One phone, call Tmo and tell them to put in a cancellation request for your old number, and swap the number with the new one that Google sent you.
