  Android without Google account
  I really like my Android phone, but I don't want my data on Google servers. First I thought, why not, but when I tried to remove the Google account they forced me to reset my phone to factory settings.
  Fortunately there is now an open-source solution to the problem: Zarafa with Z-Push. It works great and all my data is on my server. What is left is a good Android Market alternative.
