I'm pretty sure it's jail broken. When the apple logo appears and about 10 seconds later it flashes out with blue behind it. It's the iPhone 4. I don't know what version. How do I unjailbreak it? When I connect to my computer, which is windows xp it keeps saying it won't recognize my USB. I tried DFU and everything. Still when I do DFU, it keeps saying unable to recognize USB. I have the latest iTunes, I re installed it and everything. Still does not work. Also, When I go through the steps like pick my language and where I live and at the in it will say WiFi or connect to iTunes. Well when i connect to WiFi and will say activating processing and then say it won't activate. and when I connect to iTunes, well it won't recognize USB. Any clues? I would like to be unjailbreak and back to factory settings. I don't care about what is on the iPhone. Just want it back to factory. Thanks!!
