As per members request in my previous thread, i have modded FullOnSMS application for reliance, airtel and virgin. Enjoy free SMSing!!

Let me tell u first that the official means original version of FullOnSMS has a bug that it crashes after using it for one time specially for s40 users which is provided by Coolatmusic bro, so even the original version of FullOnSMS is of no use, so i have modified the server address and login syntax of Way2sms with that of FullOnSMS server and login syntax for FullOnSMS users.
Here are the download links:
FULLONSMS RIM MOD s60 v3
FULLONSMS AIRTEL MOD s60 v3
FULLONSMS VIRGIN MOD s60 v3
