Ok...one more time...
I've been reading about jailbreaking and all the benefits of it. So, I tried it using Absinthe following all the directions. Yes, I made a back up and reset the phone before. Made sure I was the admin on the computer. I do remember seeing the cydia icon after it jailbroke, but either I clicked it (which I don't remember doing) or it just disappeared. Anyway, when I loaded the back up from Itunes, I didn't get everything back. Like the phone dialer icon was gone. The Settings icon, gone. What good is a phone if I couldn't dial some one on it. I could receive calls though. Other things were missing. Tried loading the back up again and it got worse! Basically, I bricked the phone and had to reload, so I got it back to factory.
I have an Iphone 4, software version 5.1.1, I have windows xp operating system. I'm a little skeptical about trying again, but if I get some help, I'll try again
