Hi,
This is a tweak that made by bahathir from xda-developers.
It will speed up your data cellular/packet speed by compressing TCP/IP header (vj).
If your carrier/mobile network provider supporting TCP/IP header compressing, then it should work for you.

Install:
1. Extract the file above with Zarchiver or B1 Free Archiver or equivalent app.
2. Go to the extracted 7z and move the file inside it (options) to:
/system/etc/ppp
3. Change the file permission to:
r-xr-xr-x
or
r - x
r - x
r - x
4. Reboot and profit!
Doesn't work? Simply delete "options" file in /system/etc/ppp and reboot.
Confirmed carriers:
Malaysia - Celcom
India - Vodafone
United Kingdom - 3 "Three" (Maybe it should work with 3 (Tri) Indonesia)
Anyway, if your get data packet speed improvements with your carrier rather than mentioned above, please leave your comments here.
