Apps being updated for Verizon iPhone compatibility

Several iOS developers have begun to release application updates specifically to address compatibility with the new Verizon iPhone. Smule has released updates to several of its apps including Ocarina, I Am T-Pain and Glee Karaoke, listing simply “Optimized for new Verizon iPhone users” in the release notes. Similarly, TomTom has updated several of its GPS navigation apps such as TomTom U.S. & Canada with a specific Verizon iPhone 4 release designed to address what it describes as “inaccurate pop-up error messages” within the app. It is unclear whether these problems are simply due to incompatibilities with the slightly newer iOS 4.2.6 running on the Verizon iPhone or are related to hardware or network differences.
