Settings for free gprs :
APN- airtelmms.com
Proxy ip- 10.2.45.155
Proxy port- 8080 (In S.E. u can use wap mode too to speed up ur browsing)
Remember this proxy server is a mirror of 100.1.200.99 Proxy
the only diff is that it is live for mms apn too as 99 was in past
So never use this new proxy for airtelfun.com coz it will charge
u same as 100.1.200.99 apn (i.e. 30 paisa/20kB).
So just use it with airtelmms.com (MMS APN) n enjoy all msngers,
softwares n more stuff on both pc n mobile...
One BAD NEWS =>it have a download limitation
