.mobi and .biz

.modi or dotmobi I heard is the newest and fastest grown web address. It was designed for cellular telephones and other devices with small screens. A lot of cyber squatters have moved in fast to buy up the best names. I wonder if it is too late for me to get into the game? Another interesting thing I learned is that .biz addresses are only for businesses so cyber squatters are not allowed. Trademarks will also apply. I will have to be sure to remember this. I wouldn't want to get in any trouble.
