I have a Samsung Galaxy S mobile phone, running Android 2.1, and am very pleased with it (can't compare though, since it's my first device with Android).
When I had some problem with the installed Facebook application, and got some answers here fro the site, it seemed that I was using a 'Facebook S!' application and not the 'standard' Facebook for Android.
I was just wondering just now: is there a way to compare an Android on your device with a standard installation ? I , for one , would like know that applications have been written by my mobile manufacturor and my mobile operator, and which are standard.
