iPhone 5S + iOS 7.01 -- not retaining passwords?

[147798]

Anyone else finding your 5S keeps asking for iCloud and e-mail passwords periodically (haven't determined the periodicity, though).

Yep, although mine just keeps asking for my iTunes store password. It won't let me pull up any of my previously purchased apps. When I check the settings, it shows that I am signed in already. If I sign out and sign back in, it asks for the password 3-4 times and then does nothing. Very frustrating.
