I have an unlocked/jailbroken 3G running 3.1.2. After a recent Words with Friends update, the game crashes after opening. Zynga's response is to upgrade the iOS on my phone. Absolutely not. Did it before and the phone's performance went downhill. I need to downgrade to a previous version of WWF, but after I install it and try to login, it forces me to go to the app store to upgrade back to what I already had. Is there a way to bypass this forced upgrade?
