After setting up an iPhone 4S for the first time, whenever you try to send or receive mail while on a call you may see the following alert:

  • "Cannot Get Mail - A data connection cannot be established since a call is currently active."

Cannot Get Mail alert

This alert appears only when using a cellular data connection. If you have a Wi-Fi connection, you can send and receive email normally.

You can resolve this issue by updating to iOS 5.0.1 or later.
