So here's the thing: I want iOS 5 on my iPhone 4 really badly. The downside is that there's only a tethered jailbreak right now. I am currently jailbroken on 4.3.3 and use apps from Cydia more than I realize (namely SBSettings & MyWi). If I update to iOS 5 I'd lose out on those until an untethered jailbreak comes out, so for right now I'm considering a tethered jailbreak. My question is: What is the downside of a tethered jailbreak? Yes, I know it means that if you turn your phone off you need to plug it back in to keep the jailbreak. But does this mean that if my battery were to die, for example, while on a tethered jailbreak, that I wouldn't be able to use my phone at ALL until I plug it into my computer? Or does it mean that it will still turn on but the jailbreak will be gone? Thanks!
