so ive downloaded stack after i jailbroke with purplera1n and im having some problems. after i downloaded stacks and removed some of the icons from the stack, i wasnt able to move them back into the stack (or any of my icons for that matter). the stack is also in the middle of bottom part of the screen (in between mail and safari) even though the description said it would be on the far right bottom where the ipod is. am i doing something wrong? i have removed and re-installed it a bunch of times...
