Strange placement problem on 3GS device with iOS 4.2.1 - compiled with iOS 5

Question

We had a strange bug report from an iOS 4.2.1 user on an iPhone 3GS. Many UITextLabels in the application are biased in strange places. Does anyone else run into this problem.

The application is correctly displayed on all devices on which we tested, and we only heard about this problem from 2 users from more than 100,000.

This may be due to Three20 styles.
