Midweek rumor roundup: 10.5.7, 3G laptops, parental controls & more

Get your scorecard here, can't tell the speculations without a scorecard... it's the midweek rumor roundup! While the rest of the tech blogosphere is mobbing Amazon's black & white imitation of a Stevenote (yes, the Kindle DX is already on sale), we'll catch up on the open threads of the past couple of days.

Kara Swisher at AllThingsD has the most complete take on the Apple/Twitter rumor from yesterday. While it's not beyond imagining that Apple and Twitter are talking, she says, it's only part of a dance with scores of other possible suitors and an inevitable rugby scrum at the finish line.

Mac|Life is citing a source within Apple on a release date for 10.5.7, and they pin it for this coming Friday. 9to5Mac points out that Friday is an unlikely day for an OS release, but there has been a spike in support staffing at the company's Austin offices in anticipation of customer questions.

Speaking of rumors from 9to5 and Computerworld, there was a brief spotting of an QA engineering job posting from Apple (since taken down on Apple's job site) that indicated a need within the Mac group for a 3G WLAN hire. While 3G talent is naturally present on the iPhone team, this laptop-centric gig might lend more credence to the idea of a portable machine with onboard wireless broadband capability.

Lastly, the rejection of Makayama's Newspaper app for iPhone on the grounds that it allowed access to the UK Sun tabloid's notorious Page 3 girls -- reminiscent of the Craigslist app commotion -- cites the upcoming parental controls in iPhone 3.0 as a possible mitigator for R-rated apps in the future. Got something sexy or skanky in the pipeline? You may not have to wait much longer.
