I've used all iPhones since the very beginning with the iPhone 2G, and have always been running a jailbreak since then. I couldn't live without it for a long time. However, since I have my iPhone 4, I've been running it without a jailbreak for a very long time since often there were only tethered jailbreaks available. Now, after a very long time away from the jailbreaking scene, I decided to look for it once again, only to find that there are still no full untethered jailbreaks. I don't rely on a jailbreak as much as I did and I very much appreciate the work of the Dev-team, but man, Apple's improved on its security, haven't they? Is it therefore safe to say that Apple's "winning the jailbreak battle"? Edit: Apparently I wrongly formulated my post, rectification here.
