Teach Huawei u8500 how to distinguish between inbox, outbox and sent messages, and what software to download?

Eh, in the information that comes with the system, just like chatting with QQ, there is a contact person and an information box. For example, a message sent to you by a contact, and then you reply to him, all in a message box, one by one, easy to find. Sent messages will show the time, and unsuccessful messages will show that they are being sent. The software to be downloaded is generally fast map browsing, daily listening, titanium backup, ink weather, R.E manager and advanced task manager, all of which are necessary.
