Evidence is mounting that when iOS 5 debuts at WWDC next week, it’ll feature some deep integration with microblogging service Twitter. Not only has Twitter launched a new photo sharing service just days before Apple is expected to unveil the ability to share photos via Twitter in iOS, but now blogger and tech evangelist Robert Scoble is saying that “next week will be a huge week for those of us who have lived on Twitter for the last few years.”

Last week, one of the most interesting Mac programs to come out in years hit the App Store in Sparrow for Mac, an elegant and attractive e-mail client that looks and acts a lot like Twitter.

I loved it, comparing it to more full-featured clients like Postbox 2 by saying Sparrow was “the equivalent of skipping stones, not piloting a submarine.”

I decided to reach out to Sparrow for Mac team member Dom Leca and ask him a few questions about the origins, inspiration and future of the e-mail program that treats your Gmail as if it were Twitter.

Following yesterday’s story that Steve Jobs and Rupert Murdoch might meet on stage to debut the world’s first iPad-only newspaper, comes a new report suggesting not only that Apple will hold that event on December 9th, but also use it as an opportunity to unveil a new subscription billing option for periodicals on the iPad.
