Hello, I tried to upgrade my iPhone 4S to ios 7 and I didn't know I needed to be apart of the developer program. I installed it and now during the activation it says I need to be part of the developer program. Now I can't reset my iPhone to downgrade, now I just have an iPhone I can't use. I don't know what to do, BTW my lock button is broken so anything using that won't work. Can someone please help, any would be appreciated!!!
