I agree with you sir,
1. Continuous connectivity with clarity of signal than GSM i belive, truly unmatched sound clarity
2. Signal wise ( Data wise) in Gujarat we have only 2G (not evdo i belive) for RCOM, so sometime data weakens and lost connectivity, thats what i experiencing in Rajkot City
3. Call and Voice Quality Fantastic
In ahmedabad evdo with reliance works very well...
