Beg to differ Arun....though 6000 is technically more advanced, it has repoted problems like excessive heating ups leading to poor sound quality and other bugs like in GTRAN....incorrigibly, 6000 model seems a failure and soon i suppose that the prices might reduce (if the demand drops!!! )
6130 is comparatively cheaper and has a decent ground excepting the keypad issue..
If someone is not interested in Camera, go in for the steardy LG flap handset (the older model which used to cost somewhere around 15500 earlier), which can now be obtained at approx Rs.3750+GSK !!!!!!! (mind me NOT the refurbished ones...but u will have to roll them up from a dealer and not the WWs)
Another cheaper version........Anyone interested in Motorola 131 at about Rs.100-200??????..try to bug the prepaid distributors!!!!!
