Stone Design has released Twittelator Pro, a paid version of its normally free Twitter app for the iPhone. The Pro edition adds several features, most notably the ability to access multiple accounts, and quickly switch between them. Users can also pick from three different themes, and the interface has been altered to use scaling fonts, confirmation before each tweet, and limited copy/paste functions.

Other changes include speed improvements, map references, high-resolution photo uploads to TwitPic, and the ability to disable automatic correction and/or capitalization. The software costs $5, and is being sold through the iTunes App Store.
