OK first of all, apologies if this is in the incorrect place. I looked everywhere and couldn't find where it should go.
My wifi stopped working on my iPhone 3GS the other day so I tried to update the phone from 4.3.3 to 4.3.5. The iPhone was second hand and I was unaware it was jailbroken/unlocked, the update didn't work and now I can't use my iPhone.
I don't really know what I am doing and what other information you need. Please help, I will answer any questions as best as possible.
Thanks for reading.
