My iphone3GS always appears a string of English after receiving the email, as shown in the screenshot. How to solve it?

Oh, I've met your question before, and many people don't have a suitable answer. In desperation, I tried to uninstall the 1.44 version of 360 Mobile Guardian, and the problem did not appear again. Later, I downloaded the latest version of 360 Mobile Guardian 1.72, and the problem did not appear. So far, mine must be for this reason. I don't know if yours is like this. Good luck!
