Thanks. Yes, it sounds like an iPhone 4S.
However, I hate to be the bearer of bad news but the procedure for clearing the passcode on this iPhone, also, erases personal content off of the iPhone, as well, for security reasons. So, this may not be useful to you (except as a threat that the iPhone may be wiped if she does not provide the passcode?).
Was the iPhone normally synced with iTunes prior to being locked? If so, you may be able to wipe the iPhone and restore a recent backup (You can see if there is one in iTunes > Edit menu > Preferences > Devices)
I will provide the procedure below, just in case:
The following procedure is a special firmware recovery mode (DFU). It will re-install the operating system on the iOS device (iPad, iPhone, iPod touch), clear any pass codes, and then re-sync user data once it is done.
Make sure you have downloaded and installed the latest version of iTunes before attempting this:http://www.apple.com/itunes/download/
(Mac users can run System Preferences > Software Update > Check now to get the latest version for their system in most cases.)
* Open iTunes on your computer
* Connect the iOS device directly to a USB port on the computer
* Turn off the iOS device (hold down the sleep/wake button on the top) until you see the red slider and slide the red slider across to the right OR
until the device simply shuts off, if locked up.
* Hold down the sleep/wake button (on the top) AND the home button (on the front)
for 10 seconds
* Release the sleep/wake button but CONTINUE to hold the home button, until...
* iTunes should pop up and tell you it’s found a device in recovery mode, click ok and continue along for the restore
If it doesn’t work the 1st time, start from the beginning and try again. If iTunes *still* doesn't recognize the device, plug it into a DIFFERENT USB port and try once more.
If you receive misc errors when attempting to install/uninstall or sync after installation, try temporarily disabling any anti-virus or firewall software you may be running.
Hopefully, this info will answer your question. If you continue to have questions on this topic, do not rate yet, just reply back to this discussion. I will be more than happy to work with you further.
Thanks and good luck,
