Apple Legal has been busy in the past few days. Apple has officially begun protecting their iPhone Trademark. MY iTablet -- once MYiPhone -- changed their name on the advice of Jobs himself. And it appears that some of the other blog sites have now received contact letters from Apple lawyers.
In the U.S. system of intellectual property law, if you don't actively protect your copyrights and trademarks, you lose them. Apple has to do this. I'm sure Apple isn't excited about taking iPhone community sites to court, but they have to do what they have to do.
