Lol Baz, yeah it voids your warranty but mines out of that now anyway. It's a bit technical but can do done quickly and relatively easily once you have memorized the instructions. just go to
www.xdadevelopers.com and search for your phone then read ALL the information and see if you think you can manage it. If so, you could end up with a lot faster operating phone with better battery life and better photo's etc.
Just got my 32gb microSD card delivered today... unfortunately, they sent me a class 10 not a class 4 like i'd ordered BUT it might work out better for my videos and photos.
