Objective-C restart iphone or possibly another method?

Question

I read that there was no method to restart the iPhone (at least that will go through the app store), so I am wondering if you have any other ideas. Basically, at my desk, I receive "No Service"... When I go out to my car (in a service area), I remain in No Service without being able to make a call until I restart my iPhone. I've tried respringing winterboard, I've tried airplane mode on/off and that doesn't work either. The only way I've found is to restart the iPhone completely. Does anyone else have any ideas?

Thanks!

Answer 1

Your explanation is right on the money. Nothing you can do about this particular problem outside of jailbreaking.

Answer 2

Has apple changed the root password?

I've tried connecting using:

system("login root"); system("passwd alpine"); system("shutdown -r now");

It produced this in the console:

Password:Login incorrect login: can't create lock file.

Any help? Thank you.
