Someone posted a link yesterday to a guy (very sharp and knowledgeable) who gave a very detailed overview on DE-GOOGING your Android phone. Precise and detailed on what it was like to use the phone in daily realistic use. Most of the popular Android phones are supported. Very cool thing is that without all the Google spy stuff always running in the background and constantly phoning home, your battery life doubles or triples. Phones run for 2 or 3 days without needing to be charged.
Got a link?
