I'm getting the notice from iTunes that I'm running 4.3.1 and 4.3.2 is available. What the heck..., why not upgrade? But every time, for the past three days, no matter what time of day I try, I'm getting an error. It gets to 621.0 MB of 621.1 MB, pauses for a good chunk of time, and then I get this error (see attached screenshot -- basically "the network connection timed out") and the item in the Downloads screen displays "zero KB of 621.1 MB - stopped (err = -3259). 'Sup with that?!? I'm on a Windows 7 x64 PC, running iTunes 10.2.1.1. I've had no issues downloading and installing many, many apps since getting my iPad.
