Ring duration fix
No luck at all with the countless forum and other listings that say to use the long code string, *61*, etc, etc to extend the ring time as it only results for me and others with a final response of "error performing request unknown error". If you are an AT&T user, simply call AT&T and ask that they use their "Torch" program to extend the ring time past the default 20 seconds. Worked for me with the iPhone 5, now getting six rings and 30 seconds.
Now if Apple would just fix the myriad of problems with the iOS 7 version, such as decreased ring volume and shorter number of rings (like one) then to voice mail it would be a big help. This is the sole reason I had to try to extend ring time as it gives me an outside chance to hear the dimished ring and alert volumes. BUT Apple will not acknowledge the countless number of complaints found on a number of forums and also passed by word of mouth by disatisfied users.
Apple: Please fix iOS7 or provide an option to go back to iOS6 that worked.
