More than a few iOS-based Twitter users were happy to see Twitterrific 5 appear late last year with a fresh design, but were less than thrilled to go without the push notifications that many take for granted in other apps. Equality has come through Twitterrific 5.2 -- for some, at least. The upgrade at last pops up interactions as they happen, with a symbol to indicate whether it's a conversation, favorite or retweet. Push delivery isn't guaranteed at this point, however. Iconfactory is currently rolling out the beta-level feature to users in batches of 1,000 to avoid oversaturating its servers; you may have to wait awhile. The impatient still get some upgrades to sate their appetite, though, including user banners on profiles, discussion sharing through email and Droplr content thumbnails. If you're willing to pay $6 ($3 on sale) for more than what Twitter gives away for free, the new version may be a good excuse to try something new.
