Dies a restore change the OS

I am having some issues with the Calendar app since upgrading to iOS6 (notification emails are no longer being sent to invitees in my Google Exchange account). It was suggested that my iOS6 upgrade is corrupt and I should do a reinstall. My question is, at the end if the restore, I am given the option to set up as a new phone or restore from a backup.

If I restore from the backup, is the OS also updated in the restore process, in which case any issues are returned to the phone or is only the data returned to the phone and the newly installed OS is untouched?

Thanks.

MacBook Pro, Mac OS X (10.7.2), iPhone 4s with iOS5, iPad2

Restoring your phone will place a new copy of iOS on it. At the end you will be given the option to either set it up as a new iPhone or restore from a backup, if you have one (so be sure to back up your phone before restoring). If the source of the problem you're having is a corrupt iOS this will fix things. However, if the corrupt data is contained in your backup it won't (as the corrupt data will only be returned to the phone. This is why you should first attempt to Restore followed by restoring from your backup, and if not successful, save a much of your data as you can (such as importing your photos, etc.), then restore your phone again but as a new iPhone (not using your backup).
