So i have to jail break it and unlock it to use here in Canada. However i have jail broken it I think ,but cant seem to get it unlocked can anyone help me out after spending about 40 bucks online it seems i can't find the 4.3.5 one to sort it out.

it reads the Rogers setup and from the WiFi

i use MTS and it doesn't show anything on a sim card from MTS
