I've been using a tethered jailbreak since November. My serial indicated that my 3gS had the old boot rom. In reality, it has the new one. I can't go back to 4.1 because I didn't save my SHSH blobs, thinking I wouldn't need them. So I'm stuck running a tethered 4.2.1. It was a mistake, but I accepted the risks when I upgraded. The dev team recommended that I wait to upgrade, but I wanted to experiment.
At any rate, when I want to reboot, all I do is put my phone in DFU mode and launch a file. My phone starts rebooting. I've never had to reboot my phone while out. Since writing the jb guides, I have found out more information on what a tethered jb entails. I've considered making this information part of jb101. At any rate, straight from this post, http://blog.iphone-dev.org/post/1652053923/thanksgiving-with-apple in case there are some who don't feel like reading, here's the important info. Update #2 : The notion of a “tethered” jailbreak is pretty new to many people, so here’s a quick rundown on what to expect: 1 If you’re on an iPhone3G, old-bootrom iPhone3GS, or non-MC ipt2g, life is easy. redsn0w installed an untethered jailbreak and so nothing below applies. 2 “Tethered” does not mean you cannot boot at all without PC/Mac assistance. If you have not installed any tweaks that hook into important programs like SpringBoard or CommCenter, your device will actually boot. However, jailbreak programs like Cydia won’t work (and Cydia may still have a white icon). Also, certain built-in apps that had to be moved by Cydia will fail (Safari being the most noticeable example). 3 If you’ve installed MobileSubstrate tweaks that hook into SpringBoard or other important programs, your boot will actually fail (you’ll get stuck at the Apple logo). You need to use redsn0w to “Just boot tethered right now”. End of excerpt. For those of you who don't know what MobileSubstrate is, it's a dependency of Ultrasn0w, the iPhone dev team's unlocking software for iPhones. This means that you can't install Ultrasn0w without MobileSubstrate. My friend, who has a locked phone, was able to boot up just fine. I myself do not, so I cannot reboot without the assistance of my Mac. Most of you guys won't have that problem. On Jan 31, 2011, at 2:16 AM, James Malone wrote: > Thanks!
