Is the unlock pattern you speak of the one where you touch all 4 corners of the screen? If so you're in luck! I just read about this. Start at the top left and then go to the upper right lower right and ending on the lower left corner. Hope this helps
So you're saying you cannot remember the unlock pattern? The only way to get past this is to wipe and re-install the operating system. The unlock pattern was implemented for this exact purpose and cannot be circumvented to my knowledge.
