I upgraded my iPad to 4.2 in November but I've noticed since then that it's been really sluggish. It sticks when switching home screens, closing/switching between apps and scrolling through websites. Does anyone have this problem and know a solution for it? I've tried restoring it several times to no avail, if there is no fix for it I'm hoping 4.3 will fix it somehow. Coincidentally I'm having issues uploading files to my iDisk from pages when I'm finished working in them or want to move them to my laptop, it gets halfway through the upload and then tells me an error has occurred. Anyone else having this problem too?
