This is the news of all news for Sidekick owners. You can now upgrade your existing Sidekick to a leek and savvy Sidekick 3. Just head on to TMobile's website and login with your phone number and corresponding password. Then click on Phones and Accessories and then on the right side of the page click on Upgrade Your Phone. You would have to click on the Handhelds tab to find the Sidekick 3 option. If you don't want to go through this process you can call their Customer Care at 611 from your soon to be upgraded Sidekick. Too bad for the person who got it for $4050 on eBay.
