Thanks Peter,
Guess what..? I've proved you wrong. My phone is UNLOCKED now.
Even I never thought of getting it unlocked remotely.
Here's what they have done.
After so much of persuation over the phone, 3 UK agreed that they will unlock the phone for me. They got the IMEI number from me and told me that the phone will be unlocked within 24 hours and for that I need to connect the phone to the iTunes. What they do is, they will request Apple to remove my phone from the locked list and my phone will be updated when it is connected to the iTunes. Happy Life, isn't it?
Thanks for all the supports from all you guys. I may return if I get stucked with any of the features.
Thanks a million,
Tibin.
