I have IPhone 4 running with Version 5.1.1 (9B206) I would like to update the firmware, but not to the current latest version (7.1.1) which is known to be slow on IPhone 4.

In the phone settings I can only choose the latest available firmware version. Is there a way to update the phone to an earlier version such as 6 ?
