Apple on Friday will unleash iPhone Software v2.1, a major bug fix release for all iPhone owners that will include a number of other improvements that iPod touch users are discovering as part of yesterday's similarly number iPod touch update. “The [iPhone] 2.1 software update is a big update. It fixes lots of bugs,” said Apple chief executive Steve Jobs. “You'll get fewer call drops; you'll get significantly improved battery life for most customers.”
In addition, Jobs said the update will patch a number of bugs related to third-party App Store applications, namely crashes experienced by those users who've installed a large number of apps. Backing up to iTunes will be "dramatically faster," he added.
Meanwhile, some of the other “great new performance enhancements” that Jobs alluded to, but did not describe, are being discovered by first-generation iPod touch owners who've just installed iPod touch 2.1, which will be very similar to Friday's free iPhone Software 2.1 update.
