Planning to use my bro's phone while i'm looking for a new one. He's come down from the US and i'll have to unlock it to get it working here. A issues to get sorted out before doing so.
1) Where can i get it done in chennai? Richee st.? Where exactly?
2) Once its unlocked, can he use his old t-mobile sim card once he goes back? Or is there some detection mechanism that wont let him use it?
