There's hope in the sky for Punjab and Gujarat subscribers of Airtel. The reason is that working proxies for free internet access are discovered. My favorite way of using these proxies is through mozilla firefox, but it depends much on your choice and habit which ways you prefer for Airtel free GPRS. Use the following settings.

apn-airtelgprs.com
proxy : 68.233.235.54
port : 80
home page : fb.me or mobile.twitter.com

2. proxy : 75.68.49.100
port : 80
home page : fb.me/proxy/index.php?q=

2. proxy : appspot.com
port : 80

3. proxy : 176.31.222.34
port : 80

4. proxy : proxyweb.net
port : 80

5. proxy : 66.90.76.90

port : 80

Balance condition is the usual zero penny or else the rascals at free internet on airtel would only remain a dream as Airtel will deduct whatever you have in your accounts. Users of other states may try the proxies but its not guaranteed to be working for them.
