If you please, I am not a techy.. so be gentle.... I have a TMOB that is somewhat useless to me, I live in Brasil and have 2 international TABS, plus the TMOB. Here in Brasil we can buy individual Simm chips from the various carriers here. My problem is that the TMOB does on recognize these chips nor will open up the keyboard dialer....and I want to change the system to use.... is this possible? and how can I do this?
