i accessed pc internet and also internet in my mobile in both the kolkata area and in the west bengal circle thru mobile ofice...everywhere it shows speed of 460.8kbps----as my mobile(6630)is a 3G phone...so it shows only the maximum sppeed which cud b achieved by my mob not by the airtel mo.....its still sucking 28 kbps max.....at night when i download some movies by some p2p it gives download speed ard19-23KB/s....so its not possible that airtel is giving EDGE in anywhere in WEST BENGAL....thats sure dudes.....when the net got connected neither it shows E sign.....it only shows two half broken arrows in opposite direction.....as in nokia mannual of 6630 it has been clearly written that E sign is 4 EDGE and 3G sign is 4 3G and IT IS 'NETWORK DEPENDANT'
