1. Many third-party browsers, such as Baidu, QQ, and UC, are amazing. I tested the value of the UC browser on windows phone 7 for different models. The UserAgent varies greatly.

2. On the other hand, you can set the browser mode in windows phone 7 settings. There are two modes, Desktop and Mobile. These two modes have different useragents. Pay special attention to them.
