do not root your phone and than upgrade the firmware. the install will fail and your phone will tell you"The process com.google.process.gapps has stopped unexpectedly. Please try again." you will no longer be able to go onto the market and download anything. Screwed.
Unless theres a fix beware.
K so ignore my last post you can still update the firmware as long as you haven't removed CityID apk.
Problem I'm having now is that I can't find a CityID apk that will install on phone. Guess this is one reason to be wary of deleting bloat. If you do plan on moving bloat I recommend you research how to change the program you want off from a apk to bak file. Oh and if anyone can upload or point me to a city id apk for the devour you will be a life saver.
