This has been a problem to some bb users well this how to romove it,This message is called blackberry email signature, it is so embarrassing, must someone know that you are using an MTN powered blackberry smartphone? Now this is the step:

=> From From your homepage goto > Setup > Blackberry Email Accounts > Select Options > Edit

=> Scroll down to "Signature", remove what you have there, leave it blank and save changes if you don't want it to show anything there. Or replace it with something like your name or brand.
