How to cancel Apple's SMS?

Iphone SMS number cannot be erased, as shown below:

1. Open Settings, Applications, Management Applications, All, Information.

2. Clear the data after opening, which can be done by most mobile phones.

3. This is just clearing short messages. The key problem has not been solved. Maybe I won't delete the information when it is full next time.

4. If there is an updated version, the update will be fine, and the new version may not fix this BUG.
