When I go to reboot or respring I get all worried that it will get stuck or something will go wrong and I will have to restore in iTunes, what is the chance of this ever happening and should I really be worried when I respring or reboot.
I know this is a n00b question and I am not a n00b jailbreaker but it is just a consern.
Thanks for your time!
Jakob.
Yeah G'day Jacob, I've jailbroken my iPhone 3GS, was going to tell you the pros and cons, but since you aren't a 'n00b' I'll skip to my reliability experiences.
Depending on what you're using on the device, it varies, when I first jailbroke the phone, without the Corona add-on that unlocked the ability to reboot untethered, I recall having to start my phone again all the time, based on the later iOS 4 software, however with corona on iOS 5.0.1, it rarely restarts (mostly when using the GPS on low battery), and when it does, its all good, it even remembers what programs are running, and more importantly what data and programs you had on the device before it restarted, the restart normally only takes 1-2 minutes max.
As you know Apple make good reliable products, but their software leaves much to be desired, so while being unable to upgrade to iOS 5.1 yet, 5.0.1 is fairly reliable by jailbroken software standards, and I wouldn't be too worried about losing data, but again, at you're own risk.
