I got my code on 9th, but they gave instructions, which doesnot work. Out of curiosity I cut my Invalid normal Idian Sim card using dummy ATT micro sim. I placed it in my mobile, it asked for Pin & accepted it. It dtects my India Sim but as its blocked it doesnot show network. I tried my T-mobile Sim the same way cutting manually, but it doesnot detect my Sim card. I will go to T-mobile store to get help.

But for the ppl overseas I will give the contact details as promised.
