I bought an AT&T iPhone 4 from someone and it was working without a SIM card inserted. I was able to use apps and everything.
I went to Settings and erased all content because it wasn't my stuff on it.
Then it left me at a screen which tells me to insert a valid SIM with no PIN lock to activate the phone. It wont let me enter the phone even just to use it for WiFi or applications.
What should I do? Itunes wont sync it. I have friends with an iPhone 4 from AT&T, can I use their SIM just to activate this phone?
Thank you!
