Hello, I needed to do a hard reset on my iPhone 3GS and it's taking me too much time. It's taking almost 12 hours by now!!!! I did it by going to "Settings, General, Reset, Erase All Content and Settings", confirm it and then the iPhone turns off, gets the screen black with only the animated circle going on. And it's been there since then. Is this a symptom of something bad? Should I do the hard reset by another way? Thank you very much in advance for your help. Cheers!
