Still waiting impatiently for iOS 5.1 to be released? Well, carrier profiles that were recently published by iPhone carriers in Japan, France, Greece, Finland, and Sweden indicate a March 9 release date for iOS 5.1.
Apple has been slowly trickling out betas for weeks and weeks now, more slowly and less regularly than is usual for an iOS beta cycle. In previous years, the new version of iOS would debut with the iPhone in June and the x.1 release with the iPod touch in September. This year, iOS 5 didn't debut until October with the iPhone 4S, and there was no new iPod touch. So we're in uncharted territory here.
Based on leaks from the beta, there also don't seem to be many new features included in iOS 5.1. At least not yet. March 9 would put the iOS 5 release somewhere around the anticipated March release date for the iPad 3.
That starts to sound interesting. Apple has been known to hold back key features in the past, preferring to introduce them live on stage when unveiling a new device.
We're hip deep in crazy rumor season right now, so it's impossible to say what, if anything, carrier profile dates have to do with actual Apple plans. (Which can and have changed at the last moment anyway.) But things do look like they're aligning nicely.
