Does that get annoying when you browser to sites that detect iPhone for example and give you a "mobile" version of the page? or can you change the user agent back after your first request?

Perhaps you can craft a UA string that will match the regex for both cases, maybe try concatenating the iPhone and your proper UA string?

Please don't use spouted user agent strings on third party sites if you can avoid it. Reported UAs affect which browsers they support.

Isn't that like saying "please walk on the dangerously iced pavements, if accidents aren't reported they don't get gritted"?

On SafeConnect, it caches the MAC Address as exempted for a period of time. When SafeConnect pops up, I fire up my Chrome shortcut that makes my user agent "Wii". After I send a single request and it redirects me to 'unl.edu', I close the browser, and reopen Chrome with my normal shortcut (so back to normal UA).

I have to do it once every few days. I could craft a wget/curl request to run every few hours I suppose so I wouldn't have to close out of Chrome and reopen it, but what can I say, I'm lazy.
