    By blocked, do you mean carrier blacklisted? I don't believe you can use it.

    Why not try and see if it will update as you are not on T-Mo.
    Being in India they might be able to use if the India Carrier does not link it to T-Mo.

    I am a little confused, too as I do not understand what you are trying to say. Just update your phone if you can.

    From what I understand, once a phone is unlocked it is ALWAYS unlocked soyou shoul;d not worry. Updating to iOS9 will not re-lock your phone.

    I can confirm this isn't true because I just had an event happen to me while selling a phone on eBay. My wife got a replacement 6 Plus from Apple and it was unlocked. I confirmed prior to selling by paying for an IMEI check. When the buyer received it, she was complaining that it was locked to ATT (she was in Europe). I was thinking "great, eBay is full of scammers, I knew it". But she ended up sending me an IMEI check she bought as well as an invoice for her paying to unlock it. I ran another check myself and sure enough, after the phone was restored again, it became re-locked. Of course I refunded the amount for the unlock service.

    This is only an issue with Verizon iPhone 6 and 6+. Same thing happened to me.
