Three network SIM on unlocked W810i

[Spawn_Xe]

I've followed the kindly posted tutorials you guys have up here to the letter. Debranded and applied unlock patch. Now.. the phone works fantastically on voda and orange (tho it was originally an orange phone).. but whenever I put a Three sim in there i get 'Insert SIM' and cant do anythin else other than view its built in demo.

Any suggestions? please?

thanks!!

it was originally orange and works ok on other networks. Just doesnt seem to want to play ball with a Three SIM, it acts like its not even there. Is it a problem when i goto 'Select Network' (with a vodafone sim in to make it work) in settings that only Orange, O2 and Vodafone show up.. should it be showing 3 and T-Mobile aswell?

Its a CID 49 W810.. about a year n a half old.
