You need AnimSprite to show this animated logo. AnimSprite v2.02 is available here. I have used minimum animation to save on CPU & battery.

Instructions:
Install AnimSprite v2.02
Copy the attached AirTel.mbm to your phone, preferably to C:
Run AnimSprite and choose sprite from options
Now select Position set from options and position it over the default text logo.
Press the left soft key to save the position
Set the MBM speed as desired (I have mine set at 50)
