If you forgot the passcode for your iPhone, iPad, or iPod touch, or your device is disabled - Apple Support

restore is the only option to remove the passcode and yes that will wipe her phone.

It's too late for her to worry about losing anything. If she has a backup, she can restore the backup after unlocking the iPhone.

Follow the instructions in the link provided by SoN1NjA

Did she have iCloud backup enabled? You can check that if she logs in to her iCloud account in a computer's web browser. If she did not have an iCloud or iTunes backup already in place, I'm sorry but she is going to loose all content on that device. The only way to reset the screen lock passcode is to restore the phone. Without a backup already available to restore from, your only option is to restore as a new device and then re-download apps, iTunes and iBooks content and set everything up anew.
