Welcome to CrackBerry, West. While you will not be able to install 7.1 OS, you could always try a Hybrid OS that will have base files from OS 6 with files most likely from OS 7.0 and 7.1. Here is a link to the latest hybrid OS for other devices including your 9800. First time? Here is a guide on another thread by one of our top hybrid makers WuWei: Hybrid OS Installation Guide
I know it's not what you want, but, it's about as close as you will get. Please review the guide if you decide to install the hybrid. Good Luck and again, welcome.
