If you don't have the answer, don't reply. And what if I'm a Blackberry user? I'm a Galaxy S3 and iPad user as well.
For those who care:
Had the same problem last night on my GS3. Seems like that is a bit better. On my BB it's still not working properly. And now it's not just FB but Internet too. Seems like this new throttling thing from MTN is a load of crap. I thought it was only for heavy users. I hardly use my BB for anything else than BBM. 90% of the time I use my GS3.
