Hi there, Could someone tell me the difference between firmware and OS for Android. I've recently got confuessed becuase i thought it was the same? I was looking to change my supplier of Android Tablets and I was going to purchase a Android 2.1 (which is what i want) but the firmware is 1.6. What is the lowest firmware I should buy? Also, i'm a bit out of date with the chipset, is there a particular chipset I should stay away from?
