4x4x4 Rubik's Cube

My girlfriend gave me a 4x4x4 Rubik's Cube... because she knows how addicted I got to solving the 3x3x3 one :D. My friend Ralph taught me how to solve the 3x3x3 cube and from then on I was hooked, well, not hooked hooked but I spent a lot of time playing with it after I learned how to solve it. Since I got the 4x4x4 cube I spent the whole day after Christmas looking at Pogobat's how to solve the 4x4x4 tutorial on youtube... It's pretty effective, I was able to solve the puzzle up until the last part where I met monsieur parity... Yeah, that bastard parity... I tried to follow pogobat's instructions but it was just too fast for my poor widdle brain. See my parity Riiiight doown here..... See, the two opposite corners are not in the right position. Sucks... I wish I could solve it before new year hehehe
