I have two offers for my iPod, the 7125 runs on 2.3 android and the 8850 is 4.0. I'm new to android and not sure which one is better, the specs on the 8850 are vague, not sure if it has Bluetooth. Could you update the os to 4.0 or what ever is current. Is one more outdated than the other... I need help making this decision! I have little time too!
