Use iPhone 4s as iPod Touch, Can't Activate

Hello all,

I have an old Sprint 4s that I'd like to keep using as an iPod Touch and don't need cell service on. I wiped it clean when I got my new phone and haven't touched it in about a year. I turned it on and it started to take me through the activation process but I keep getting the error message "Your iPhone could not be activated because the activation server is temporarily unavailable" So I plugged it into iTunes and when I click the on the iPhone in iTunes I get a message that says "Your request couldn't be processed. We're sorry, but there was an error processing your request. Please try again later." I tried restoring the phone and got the same messages. Then I tried putting the phone in recovery mode, restoring it, and I got the same messages after it updated the ios.

I had a chat session with Apple and after some troubleshooting to do things I had already done, they transferred me to a supervisor who basically said "you need a support sim, go search the forums." Anybody know anything about this? Is the sim card really the problem, and how do I get a support sim card?

Thanks in advance.

Matt
