You have to change your CSC code but also need to have a sim card from that country inserted to get the OTA updates, so I would not suggest this as you wouldnt receive any updates in the future. I have previously changed my CSC code from H3G (3 mobile branded) to EUX to get beta software but this worked fine as the beta was out in the UK and I had a UK sim card in my phone.
I'm sure the beta will be released in the UK soon if it has hit India.
