As said above I have an iPhone 3g and I am JB on 3.1.2 and I installed winterboard and started messing around with some themes. One theme has a constant changing background picture and when I slide from one page to another everything slows down. Same as when I open an app. I even reboot to make sure I don't have any unnesacary apps draining memory. My question is if this is common or is there something Im doing wrong? Thanks in advance!
