Hey everyone, So I've just come across this issue, and maybe someone can shed some light. I did a search, but didn't find anything on it. I jailbroke by 3GS from 3.0 to 3.1.2 using PwnageTool 3.1.4 a week or so ago. My AT&T signal was lost, which I replaced easily due to the 'cosmetics' of it. However, I think this issue is more than purely 'cosmetic'. I tried locating my iphone through the "Find my iPhone" feature in MobileMe, and I received an error saying that my iPhone was not connected to a data network or does not have push enabled. I have checked my Push settings, and it is indeed enabled. Can anyone else use "Find my iPhone" with a jailbroken 3GS with the no network signal issue from using PwnageTool? Is there a fix for this? All the "fixes" I've seen have been cosmetic in nature. I did read on the dev team wiki that if you get this then you didn't jailbreak properly, but I'm sure I unchecked the Activate my iPhone option when asked. Any thoughts?
