This is not exactly a tweak just a way to reduce costs.
We all kno Glo has changed 1k sub to 1500.
The best option now is to get a new airtel sim(sims bought since january also work)
Buy 1000 Credit and load it with *555# and get 1gig free.
Check your free gig with *556#
When the free data has finished,Sub for the BB10 Bis *431# 3gig for 1000.
Then change your android imei to bb10 imei 35695050588478.
And you can now brows with the bb10 sub on your android.
