If I installed Speedmod Kernel or any custom roms, do I still need to install Lagfix ?
I'm new to Android, so a bit confusing for me.
For iPhone I only need to jailbreak them "AHEM"
But for Android seem like i got to more lot thing to install..duno whr to start
Basically for Android, you need to Root to gain administrative access of the phone (viewing system folders, accessing system operationes etc.) and access paid market. No need Root to Ahem.
Lagfix is for SGS only coz of Samsung proprietary file system (RFS) which will lag the phone after months of usage or when it reach certain size of storage space (subjective, no specific size).
If you're running Custom ROM of Android version 2.2.1 and above, you can survive without the lagfix. Only applicable for 2.2 and below.
All custom kernel for SGS have lagfix options. Its up to user whether to activate the fix.
