Hi, I recently updated my iPhone 4 to iOS5, but have encountered some problems afterwards.

1. Location services is "forced" off. Meaning that the text is grey and I am not able to flip the "switch" to on(settings->location services->on/off)

2. In the settings menu the buttons for iCloud and twitter is grey and I am not able to access these.

Additional info, I have OS X10.7.2 and iTunes10.5 installed on my iMac, and iOS 5 is "successfully" installed on my iPhone 4.

Help would be appreciated.
