Anyone who is good with technology?

So I have an iPhone 3GS and I'm trying to update it to the latest ios but when I go to software update on settings it just says checking for update. I have left it for extended periods of time but it still says that. My phone is jailbroken so I'm presuming its because of that. But I can't restore it because I can't connect it to iTunes. So I'm kind of stuck right now. Any help would be appreciated

Even if you were to somehow unjailbreak your device, there wouldn't be any updates for your device. IOS 7, for example, is only available for the iPhone 4+, and not for the 3GS.

You are correct, you can't update while it is jailbroken because then the jailbreak will be out of date. If you are ever "successful" the phone will lock up and the sim card will not work with it. Try useing google to search for a solution.

  • Why do people want to get the latest technology? I still have an iPhone 4S, it's working fine except the home button is messed up but I can live with it. Because the phone can still be used to call and do what phones do. Why do people feel the need to buy the latest Phone when they don't need it?
  • Who knows anything about music technology/music making computer software? So I basically made a few different iPhone recordings; Voice, two guitar riffs, piano. And I would love to put them all together, I want to make music! Anyone have any idea of safe, preferably free (super broke) music technology software I can download? To mix, add, mess around with different sounds and tracks?
  • What's the most complicated human technology so far? This is for you thinkers out there. Say you could live forever. And you had the exact plans on how to make a technological object. What object would take the longest to build? Remember, you would have to start from complete scratch. That means finding a rock, to mine other rocks, to make metal tools, to make more metal, to then form into everything else. I think an iPhone would be one of the hardest/ longest things to build. What do you think?
  • What are some good persuasive essay topics about technology? I'm writing a persuasive essay for my college English class and I want to do it about technology, well something in that broad category. I'm really techy and love computers, video games, etc… I was thinking something like "are video games bad for you?" or "is the iPhone really the best smartphone?" or "Which is better: Windows or Mac?" Just looking for some advice.
