If you are unable to access the main Site having upgraded to the new version of iOS it may be because some settings have been reset within Safari.
Check the following two options within "Settings -> Safari":
- Accept Cookies: From Visited
- JavaScript: On
If that fails to work, clear your browsing history by clicking on the Bookmarks Icon, going into "History" and choosing "Clear".
Worst case, power cycle your phone (turn it off and on again).
Don't forget, we have a cut-down version of the Site for your device at http://www.adultwork.com/iOS/
