I am using an iPhone with a Vodafone SIM

I am using an iPhone with a Vodafone SIM from Nov 5th. However last week I did a serious mistake of updating it with v1.1.2 and the phone became a brick. It simply did not recognize any SIM and would only allow emergency calls. However after 3 days of hard work I successfully unlocked it without a Wi-Fi connection and is using it on vodafone. It works fine. So if Apple is saying the v1.1.2 can’t be cracked it’s not true.
However I am not able to use EDGE with APN: www on vodafone. It says “You are not subscribed to EDGE” although I have a GPRS enabled SIM card.
Can anyone help?
