How to Install Whatsapp on a wi-fi only tablet

A lot of you must be wondering why whatsapp doesn't work on a Wi-fi only tab. This question arises because you can continue running whatsapp even without a SIM in your android phone.
The answer to this is that Whatsapp requires your SIM only for registration. This is done to avoid misuse of whatsapp by users.
However for those who don't have an Android phone but might have an android tablet, I have some good news. You can run Whatsapp from your tablet. HOW???
(This method works on Motorola Xoom, Samsung Galaxy Tab P1000, Micromax Funbook and almost all other tabets.)
Lets see--->

REQUIREMENTS:
1. Rooted tablet
2. Rooted android phone (Borrow your friend's or sibling's)
3.Titanium Backup Pro installed on either device

STEPS:
1. The first step is to root your android phone and tablet.
For that you can my post on Rooting your Android

2. Install Titanium Backup Pro on both the devices.

3. Now from the android phone take a backup of Whatsapp

4. Now, connect it to your PC via USB, enter mass storage and in your sdcard, look for the folder "Titanium Backup"

5. Copy all the files in this folder starting with com.whatsapp

6 Now connect your tablet to your PC and copy these files to the "Titanium Backup" folder of the tablet's sdcard

7.Now disconnect your phone and tablet from the PC.
