Faster cellular data speed

3 days ago, I did a change in /system/etc/ppp/peers/pppd-ril.options.
This is the orignal content of the file.
Code:
nodetach
debug
noauth
defaultroute
usepeerdns
connect-delay 1000
# Don't remove the user/password lines. They are required to make PPPD authenticate itself with
# the BP when doing Simple IP (SIP). The BP will replace the user/password strings with the correct
# values when authenticating to the network-side PPP peer.

we may able to get better 3G network speed. The change may enable the Van Jacobson style TCP/IP header compression. Your cellular network may or may not support this feature. My 3G cellular network (Celcom Malaysia, HSDPA 3.6Mbps) seem to be supporting this feature.
Before the change, I got (down/up) 3.4/0.5 Mbps, but, after the change, the result is quite impressive as we can see in the screenshot. Sometime, I got about 2x of download speed when download podcasts MP3s, from 400 kBps to upto 800 kBps.
Now, for temporary, I am using Samsung Galaxy S (GT-I9000, 2.3.6 GB Stock, rooted using Framaroot). Just now, I add an options file into /system/etc/ppp directory. I attached file in this post. Feel free to try.
1) Attention, if your device NOT has /system/etc/ppp/options, you can put the attaxhed file into the directory /system/etc/ppp
2) If you have the options file, Back it up first.
3) Remove any novj nobsd .... options int the file.
4) Append .or insert the contents of the attached file into the existing options file.
Again, I tried this hack on Samsung Galaxy S. and I achived the similar effect
Good Luck, and don't cry over here if you failed. You should know how to backup and restore from backup at the first place.
I also like to thanks to everyone who tried and gave feedbacks.
Please share this hack with others, especiallay the ROM developers, and remember to link back to this thread.
Thank you.
Updates:
I attached screen capture of the Speed Test's results from Samsung Galaxy S (GT-I9000).
We can see the data link speed improvements.
There were mixed results, due to several factors.
