hello all,sorry for the double post but i didnt know what section would be better to get the info.. im new here and hope to find some help..heres the situation--i work for a big company and they just switched from cingular to sprint..they gave us all new phones(samsung a640) they are calling all of us into the office and locking out the camera feature from our phones..i want to be able to use mine and want to know how i can get around this 4 digit code they are locking us out with? i already bought the data cable so i can load ring tones and so on..would the cable be of any use to get around the lock? or do i need to do a master reset? any help would be greatly appreciated!!thanks!
