Anyone who had been experiencing battery drain issues with 10.3.2 and prior 10.3.3 betas, I'm rather interested in hearing if 10.3.3b5 "cures" that up.
Given that Apple Support had been having users downgrade from 10.3.2 to 10.3.1 to remediate the issue (which requires iTunes, a computer, downloading a 1GB+ IPSW, and do a full backup and restore) but then closed the signing window for 10.3.1 last night, I'm of the opinion that Apple finally tracked down what was causing the problem--or, at least, believe they did--and it went as far back as 10.3.1 (which would mean that the 10.3.1 downgrade wasn't necessarily the "fix" the "pain" warranted). In that case, Apple chose to close 10.3.1 (which screws the jailbreakers) and their plan would be to just assuage afflicted users for another week or so when 10.3.3 ships and finally resolves it.
