well one thing, i would like to ask every person here on this forum, what is the basic difference between download manager and download accelerator!!! if we are clear about this.. we can do good things.

Regarding speed upgrades, i can tell u one thing, its easy to use tweaks and other illegal softwares if you are using the internet frm local cable wala... if you are dealing with companies like airtel, man, dont even try it.. initially u might got success however in the end.. its u who is going to loose big way... So just for 200-300 dont act smart which can land up u in jail..
