i have a white xperia play, so i wanted a white cover
so i need to buy this battery
white colored Cover, but only 2600mah
because i would have the maximum of power i bought this battery too, and hope, this battery fit to the other cover
3600mah, but black cover
all in all i spend 22€ for 2600mah and 3600mah, black and white cover.
Maybe i will sell the black cover + 2600 mah battery on ebay, when all fit together.
I will report,
best regards, bikerboy030
