data issue after update

[Corcorz]

I have an unlocked s2 LTE. After updating my phone from 2.3 to 4.1 (gingerbread to jelly bean) my data stopped working, even though I can still place texts and calls. I tried a battery pull, removed and replaced my sim card, yet nothing has fixed the problem. Also, in the about phone section, the status of the "mobile network state" is disconnected.

Does anyone know how to fix this problem, or have any suggestions?

ok so i fixed the problem. Fido and Rogers it were both no help, even though all they had to do was advise me to fix the ASN names and values.
