HOW/WHAT'S TRICK USING QUERY?

trick using query is a trick that utilizes operator's free host to get free access by editing the server in handler application as opmin handler, bolt handler, etc

how to?

simple: first, of course you must have handler application, it may be opera mini handler, bolt handler, uc handler, etc
and two, or the last step, if/after you get a handler application. run the application, then you'll find some fields like server fields which available in two choices, "socket and http", front query, host, etc
and all above is what you must set in order to get a free access.. that's it!

but there are some phone types that a bit troubled to get free access this way (or even by using apn, perhaps), like:
1) nokia s40 (Java) type 2330, 2700, 3600 slide(new), 5000, 5130, 5200, 5220,
5300, 5310, 5610, 6300, 6500, 6600 slide( baru), 6600 fold, 6600 8 Mp, 6700 c, 7210 supernova, 7310 supernova, 7390 ,7610 supernova, etc

2) old nokia s60:

3230, 6270, 6260, 6600, 6620, 6630, 6670, 6680, 6681, 6682, 7610, etc
so, if you are a user of phone types mentioned above, then you obviously need to first download prov file before testing your trick
