I last used this phone over a year ago. Was having problems due to it being jailbroken, so I decided to reset it to factory settings. Unfortunately, even now the iPhone seems to be jailbroken, as it has a golden apple icon instead of my broadband logo that I installed when it was active. I believe this is why I cannot get past the activation server ("is busy, try again later"). I have tried several methods I found online to attempt to bypass the activation, from calling an emergency number to putting my iPhone in the freezer, to no avail. I would try to restore it through iTunes, but if memory servers me right I already tried this last year and it did not work. Plus, no computer seems to recognize the phone- I have tried via USB in Windows, Linux and MacOS, in different computers, but the phone is not detected. Any advice on how I should tackle this problem?
