I thought about trying the "strings" command first, but I didn't expect that the password would be just laying there. Even if I found the "SavedPassword" string, I couldn't use it the way I did without jailbroken device, because configuration file that contained the saved password wasn't embedded in the application. The password was actually written to configuration file on the device first time it was used.
