BB Z10 - Update Issues

Hello everyone,

I finally got my hands on a BlackBerry Z10 a few days ago. After setting the phone up I wanted to do a Software Update to version 10.1.0.2312! It seemed to install perfectly, no errors or anything but I still get prompted to update to exactly that version although it's already installed! Tried to reinstall it several times but no luck! I'd really appreciate your help!

Thanks in advance!

Phil
