Guys,
I would suggest downloading the IPSW file directly from the Apple. Please find the relevant links from the website I have mentioned below.

Please a download manager such as IDM or similar one. What a download manager does is open Simultaneous links to the server and hence maintains the download speed over the entire file.
Then update through iTunes either through dfu mode or updating.
I don't have a very fast connection. I got a 4Mbps line and I was able to download within an hour. That too just after the release when the servers are thrashed the most.
Let me know if helps.
Thank u for ur help.
It's still the same as other links. When I tried to download it and it was too slow and failed. Then you mentioned IDM and I downloaded that program.
Now I am still on very slow speed to download it but at least it keeps going. Maybe I will finish it by tonight..
I just don't understand. I can download other stuff fast except from apple. It's so weird..
