T-Mobile 8320 here. I just unlocked with the official t-Mobile unlock code which was accepted fine. The instructions stated to go to manage connections and turn them all off then unlock the turn them all back on. I did it. I know have three dead applications. BB weather, Stock viewer, and Opera Mini. My BB browser is working fine as is crackberry link and Vigo. I did a battery pull and keep getting open tunnel errors on those three aps. Did the unlocking affect them? I check my WAP settings and they are fine.
