Hey guys. Earlier this morning I decided to Jailbreak my iPhone 3gs in order to get Siri. After jailbreaking and during the installation of Siri, I received a mass amount of phone calls which caused the download to freeze and caused my phone to lock up. This was a tethered Jailbreak which required redsn0w in order to work. So I tried re-booting but I couldn't get past the pineapple or regular apple screen, so I did a factory restore back to iOS 6. Now I'm unable to get past the activation screen. My phone just says 'No Service'. I bought the phone from Amazon and activated a sim for prepaid. I have no clue what I've done to get it stuck where it's at, but any help would be appreciated because I'm clueless on how to fix it. http://www.idownloadblog.com/2012/09/19/how-to-jailbreak-ios-6-and-install-cydia/ <- That is the jailbreak that I used.
