If you have your iPhone 4S in hand like me then chances are your still trying to activate your phone.
Activation servers and being flooded with activation request causing the servers to just flat not respond. The message from iTunes or on the iPhone 4S does state you will receive an email notification once your activation is complete. However, if you are like me you cannot wait to try out your new device. I’ll keep trying every 20 minutes. Can you wait for the activation email?
Some people are saying they wish they never got their device because they are unable to use it now that they have it. Just hang in there it will all be worth it in the end.
