This would be my one pet peeve about this iPhone 4s. I cannot find an answer as to how to change the number of rings or the length of the ringtone anywhere. This should be a basic option of any cell phone, in my opinion. My phone rang today during an inconvenient time and I cringed until it stopped. Is there even an option to "ignore call"? I loved that the Evo could set the number of rings or I could ignore the call or take the call. I don't have that option with the iPhone and I don't like that. Any suggestions?
