I tried to jailbreak my iPhone 4 (version 4.3.3 and firmware 04.10.01) by logging into
www.jailbreakme.com on my iPhone 4's Safari and installed Cydia. I'm not sure if it was jailbroken and feel very uncomfortable with it, so I tried to remove it. Go to Cydia --> Manage --> Cydia Installer --> Remove --> Confirm
After I removed Cydia, I tried to erase iPhone to turn it back to a new set. However, the screen showed the Apple logo but it was not running. I then restart the phone and found out my photos are still there. I tried to install back Cydia and repeat the procedures twice but still I cannot erase the phone.
I know it sounds a bit clumsy of doing these, but I just feel very uncomfortable with it. Please help =(
Also, installed Cydia does mean my iPhone has been jailbroken right?
