If you have insurance and have tried isolating out any possible nature of issue, you should be able to contact CS and see what they can do for you..
xxlaviebohemex, I understand the frustration your experiencing with your device. I researched your issues and was able to find that the freezing issue has been lifted up to our product managers and is being looked into. I see you posted on August 29, 2011 and we just issued a Software update on this day. I listed a link below to review additional information about the enhancements and steps to download.

If you continue to have issues, you can try a factory reset. Performing a hard reset will remove ALL data including the Google account, system data, application data, application settings, and downloaded applications.
