My wife's recently purchased iphone loses signal when it sleeps and therefore misses cals. I have found a solution on post 188 of this thread: http://www.hackint0sh.org/forum/show...t=7699&page=19 but this is not a true solution. Erica Sadun also has a work-around with something called John's tool.

We are within the fourteen day return window and would like a phone that does not need a work-around. If I shift+option update to firmware 1.1.3 will that restore the phone to its original factory state? If not, how to restore the phone to its original virgin state?
