thanks a lot for helping me out in the 1st case.....
in the 2nd case (unlocking T-Mobile) i applied both of your techniques, but none of them couldn't remove the code...


in both cases, whether it's siemens or t-mobile, whenever i try with XDAunlock, it says "error getting unlock code" and it always asks for the unlock code, "SID".

how can i get rid of this problem?

TIA
