iPhone 3.1 Fixes Deleted Email Bug
You may remember that in iPhone 3.0 a bug was discovered which kept email messages on POP accounts from being properly deleted. A demo of the bug can be seen here. At the time it was believed that Apple was aware of the issue and that a fix would likely appear in the 3.1 update.
Just as we expected, several people we’ve talked to report that the bug seems to have been resolved in iPhone OS 3.1. In fact, the issue may have been fixed earlier on in developer preview builds of 3.1. Good news for those of you worried about the security implications of this bug!
