Hi there, I found that the iSwifter app did time out quite a bit and that was with a good wifi connection. It seemed very laggy and jumpy when trying to play games on Facebook. It has gone through several updates, so not sure if you update yet.
Also, whenever an app is misbehaving try to do some of these immediate fixes:
Force the app to close down*by pushing the home button twice to bring up your multi-task bar. This will show all the apps that you have visited. By long pressing the app in question, it will begin to jiggle-press the red circle with the negative sign on the app. It will only quit the app and not delete. Than try to re-open the app and test out.
If that doesn't work, restart the iPad by pressing the power switch down to power off.
Third is to do a soft reset by holding the power switch and home button together until you see the apple logo. Hope that helps!
BTW...I moved this to the Help section.
