For those using iOS4, one of the most important things you can do to improve the performance of Live Cams is to double-tap the home key of your device, then press and hold one of the icons that appear in the lower tray. This will show all of the icons for the background tasks with little red minus signs next to them. Remove each of the icons until all that you have left is Live Cams.

Most background tasks don't actually do anything while idle but any network activity will be noticeable in an intensive app like Live Cams. We have also noted that several GUI elements of the app are "laggy" in iOS4. Apparently the graphic updates in the new firmware are not as fast as their previous counterparts. We would recommend staying with OS 3.x if possible.
