Motorola Droid RAZR users itching for the 3,300 mAh battery of the Maxx? Well, look no further. For $109.00 you can convert your Motorola Droid RAZR into a RAZR Maxx with a do-it-yourself kit. Not a bad price for a full conversion kit. Before you rush out and buy the kit you will have to wait until April 30, 2012 due to the kit being on back-order. So who's going to be picking up the conversion kit?
