I accidently deleted a chat on what's app, how do i get it back?

I have an iphone 4 and want to know how i can find chat history or just get that chat back as it was important.

WhatsApp doesn't store any chat on their servers. However Apple does provide a process that allows you to retrieve deleted data. If you synced your iPhone to iTunes or iCloud, you may be able to retrieve your information. See the Apple site for info on how to do this.

To prevent losing your chats in future, you can email yourself the chat history if you would like to save a conversation:

> Load WhatsApp
> Go to Settings
> Scroll to the bottom and select [Email Conversation]
> From the Chat History screen, select the conversation you would like to save.
> Select if you want to [Attach Media] or email the conversation [Without Media].
> Enter your email address and hit [send]
