iOS 4.2 for the iPhone 4 (and other generations) is now available – it includes a number of new features related to printing from the iPhone over wifi (AirPrint), streaming audio and video to AirMusic and AppleTV devices. Neither of those are particularly exciting to me since we don’t have any of those devices. The one new feature that I will make use of is that you can apparently now have custom SMS/MMS text tones and separate tones per contact.
Hopefully it’ll work well and it’ll be simple (and free) to make custom text tones from mp3 files – looks like it could be a while before I can find out as the download is crawling along. I suspect Apple’s servers are being hammered with everyone trying to fetch the latest update.
