I uploaded a few photos onto an iPod Touch 2nd Gen and when I view the photos "fit to screen" they are a bit blurry. But if I zoom in, for about a second it is a bit soft, then sharpens up...and if I then zoom back out to "fit to screen" it is sharper than it was to begin with. So, to view it sharply "fit to screen" you must zoom in and then back out. I am not sure if I'm conveying this clearly...but has anybody had similar experiences? Does it do this in the 4th generation?
