iphone 4s 8.3 Update Issue

Good Afternoon Everyone,

I am currently attempting to update one of my IPhone 4S Devices used within my current Job Role however i am encountering an issue when attempting to process the update via the device itself.

When attempting to "Download and Install" the 8.3 Update I am being presented with the Terms and Conditions for acceptance.

Upon accepting the Terms and Conditions for all required forms the window then closes returning me to the Iphone Home page with no download having been initialised nor any update installation begun.

Attempts at the following have not resolve this issue:

1. Restarting the device

2. Clearing the Cache and Files associated with the Safari Browser.

At current, due to organisational policy's, we are not allow to install the ITunes software onto the system so this update is required to be performed via the mobile device only.

Any suggestions would be appreciated. It should be noted that a factory reset/Hard reset is not a viable solution due to this being a work device.

Regards
