I finally decide to upgrade to firmware 1.14 and work with iliberty + instead of Ziphone. I did a restore via itunes since the DFU mode was hard to get since you have to be quick. The iphone did restore and I was able to install iliberty +: jailbreak, activation, cydia, you tube fix. I had the original sim card that came with the iphone since I did not want to put my own ATT sim card while freeing my iphone. The installation went well but now that I tried to put my ATT SIM card it does not recognize it. I just get some ...strength bars without the detecting my card? any suggestion? please help.
