Is the ability to use both frequencies available only on the newest models? I have a lot of 2.4GHz interference where I am (Manhattan) which I have bypassed by using my Airport Extreme in 5GHz 802.11n/a mode. This is great for my main box and my laptop, but it means that my phone can't connect to my network anymore (It doesn't support 802.11a either). My Airport Extreme is about 2 years old, it's the one that has 802.11n but only 100Mbps Ethernet. Am I out of luck?

My Airport Extreme has the following radio options:

• 802.11n (802.11b/g compatible)
• 802.11n only (2.4GHz)
• 802.11n (802.11a compatible)
• 802.11n only (5 GHz)

I could see instances where it could hurt a company NOT to check social networking sites. If a prospective employee's profile indicates a tendency toward racial or sexual discrimination, for instance, and the person was hired in a supervisory position, then acted in a discriminatory manner, those discriminated against may be able to argue in court that the company was lax in its hiring practices, which would make it responsible for the discrimination due to its lack of research.

Or their profile might indicate that they make a habit of checking out other people's profiles, which should be grounds for you not to hire them.
