How Install old version of whats app when i insatll old version then itS SHOw this is old version install new bt i want to install old version so please give me solution

Supercell do not offer two versions of the game, thus you can not play the old one and remove the new... You may play only the current version of.

Check if there is a new version for whatsapp and unistall the old version and install the new one. Should now work.

The authorisation Failed message might be due to several reasons.

1) May be due to that the MIDlet is using APi's that are not supported by the phone.
2) Also might be due to some problem while Signing. It is not necessary that the app needs to be signed. But Signing will makes the app trusted and remove the permission messages.Hope these links help you

the new whatsapp app is not running on a iPhone 3G with iOS 4.2.1 as it is too old...
- but there is a workaround which you may try:
It is possible, a bit tricky, but possible. First, you'll need to download the Whatsapp app through iTunes on your computer, this will make it show up as "purchased" in your library.
After that, open up the App Store on your iPhone and go to the 'purchased' tab. When you try to install it this way it will tell you that you need iOS 6 or higher, but will also ask if you would like to download an older version of the app. then click on download.
- again step by step:
1) Open up iTunes on your computer
2) Go to Store (left hand column) ->iTunes Store
3) Search for Whatsapp; - download the app
4) then open App Store on your iPhone
5) Click on 'Purchased'
- you will have to install Whatsapp by clicking on it as usual.
App Store will ask you: "Download an older version of this app. The current version requires iOS 6.0 or later, but you can download the last compatible version.",
- then click on Download and it should finally work.
