Apple has recently released iOS 5.1 Beta.
Apple users expect that iOS 5.1 would remove various bugs that were in the previous versions.
It is too early to assume whether it would remove the bugs or not. However, a new issue with iOS 5.1 has come to light that it would disable the popular home screen Settings shortcuts.
It appears as if the ability to reach iOS devices by URL is no more in your iDevice.
This would not matter if Apple builds shortcuts for Settings toggles into iOS.
It remains to be seen how many bugs iOS 5.1 would fix.
