I jailbroke my phone last week hoping to use MyWi went on went to training in El Paso. The network in this area sucks so I never got to use it. I didn't want to reformat till I got home this week but this morning my 3GS just crapped out on me. I tried reformatting it and it won't even reformat with the original Apple update that I downloaded from iTunes. I used the custom firmware from PwnageTool and I thought it worked but now I'm stuck without any network and a greyed out WiFi option. I really need to get this to work by the time I fly back home on Thursday. Anyone have any options for me? Thanks!
