Twitter's API rules haven't exactly made life grand for third-party clients, but that's not stopping one of the larger names in the sector from pumping out a redesigned version of its famed app for iPhone 5 and iPad. The Iconfactory's Twitterrific 5 for Twitter (yes, that's the full name) is now available in regions where it's official December 6th, with the rest of the world expected to see it in the coming hours. It's a completely overhauled and redesigned effort, boasting a unified timeline, support for Apple's newest iOS devices, "robust" VoiceOver support, custom themes, pull to refresh, and plenty of other power options for those who'd be willing to pay for such luxuries. Heck, there's even offline support for posting, favoriting and following. Early adopters should be able to snag a copy for under $5, but the introductory fare is slated to expire at an undetermined point in the future.
