Next-generation iPhones likely to focus on internal improvements.
iPhone 3.0's Parental Controls to Loosen App Store Restrictions?
iLounge reports that Makayama's Newspaper(s) [App Store, $0.99] application was originally rejected due to inappropriate online-content (images of topless women) from the UK's The Sun tabloid. Apple informed the developer that Parental Controls have been announced for iPhone 3.0 and that it "would be appropriate to resubmit your application for review once this feature is available."
This suggests that many of the "offensive content" reasons for App rejections may go away once 3.0 is available. For now, Makayama has simply removed the offending newspaper from his application.
