This is not a hack,but u can browz totally free using teashark,ucweb etc.But teashark fails to initialize on many phones.So ucweb is a btr option.Visit
www.ucweb.com from pc or wap.ucweb.com from mobile.The version 5.1 is automatically configured and browzn using airtel live setting is absolutely free.Version 6.0 is available but by default normal browsing charges apply.U need to change the default settings of ucweb6 to browz free.
I have been using ucweb5.10
for the last 3 months.Even this posting is done using ucweb.Start using it now.
