my 2 cents on this.first of all railwire is only in selected parts of bangalore like Whitefield and Kadugodi. just recently they've covered Madiwala circle. i'm calling them from the past 1 year or so and they just say it will launched in your area in the next 2 or 3 months. as for airtel, my friend got a 256kbps Unlimited airtel line. he downloaded a lot of movies the first month he got the connection. after the first bill now he is experiencing lower speeds. he used to download at 30-32 kbps in the first month. now he is downloading at 18-20kbps. what does this mean? do airtel monitor what you are doing and have a control on your bandwidth?bsnl to me is good. have'nt had any problems with it. i suggest you go for the 750UL+ plan.
