I have just submitted a bugfix update for NewsRack 2.5 that should help with the most common problems that users reported for the new version; specifically:
- Fixes compatibility issue with iPhone 3G and iPod touch 2nd generation, running iOS 4
- Improved performance for opening articles and the sharing menu
- Fixes an issue with hosted Google accounts
I apologize if you experienced any of these problems in 2.5 and I hope that Apple makes the new version available as soon as possible.
