The latest version of Voice4u (for iOS) is available for download.

This update is mostly for iPhone 3G with iOS 4 users. Based on several feedback in the last month, we’ve noticed that the application occasionally crashes at initial launch. We thought this was due to memory management or limited available physical memory. But neither was the case.

At first, we were unable to reproduce this phenomena. After hours of experiments and research, we have learned that the iOS actually terminates the application if it takes too long to load (technically in the app delegate).

The updated application executes the time-consuming initialization in the background so that the iOS does not terminate the application.

Hopefully, this update will resolve the issue 🙂
(And the new iOS 4.2 may improve the performance of iPhone 3G as well.)
