I'm really glad I didn't upgrade from my 3GS to the iPhone 4. My jailbroken 3GS running 3.1.2 is flawless and I am more than pleased with it. However, it would be nice to have the new screen, new design, and camera flash. I do plan on upgrading in the future, once some of these issues are hopefully worked out. So who else is happy they have not upgraded yet?
