So I had a 8100 (it broke) so my brother sent me an 8120. I havent opened it yet since I know there is an 8130 around but the problem is, I don't know the difference between them.
Is there any huge difference between the 8120/30?? Is it worth selling the 20 and getting the 30?
ALSO
I know the 8100 has the color pearl app and I was wondering if you thought it was possible for me to take apart my 8100 and switch the led pearl thing with the one in the 8120/30
