This is the airtel tweak, change the year of the date of your phone to 2008 while you leave the day and month correct;
Text the keyword bizday to 440 in text message for free while the #200 is deducted from your phone, you will be given 200 MB that can extend to 30 days validity.
You can now change back the year to the current one.
@Godmother, watchout for the MTN cheat on opera-mini tomorrow.
