Should we add India to a list of business unfriendly nations then?
Blackberries, iPhones and other e-mail enabled mobile devices are pretty core to many business travellers' day-to-day lives. I could see quite a lot of people re-thinking hosting conferences or meetings in any country that has a blanket ban on a Blackberry devices.
This will just damage the Indian economy and tag it as somewhere that's unfriendly to internet technology.
