my sme set only HSPA no + so it mean? HSPA + = LTE?

Take out your ext sd card if you worry about this

Guys, I got 2 questions:

1. Once rooted your phone and change kernel only, do you still receive official update if you get JB?
2. For those who rooted their phone, what kernel do you use? Siyah macam long time no update for ICS part. Now I am currently using Phenomenal. Any others I should look at?

Setting > Wipe.

If you don't think format memory, it won't format it.

Nope. Wipe using setting there will not wipe your internal sd if you did not think format internal memory. If you think format internal memory,  then yes it will format.

Factory reset using your phone setting will wipe clean your phone internal storage.
If you do wipe data/factory reset via CWM..the very FIRST time you do it will wipe clean your internal storage. The second time wont wipe your internal storage anymore.

you wrong, have some rubbish data if you use wipe only, better use dial code method very clean, i can confirm this

not delete all files don't worry
for my case is it will delete the game data that I use directory bind move to micro sd
*the game data I means is the big game data, like asphalt 7 need to download a big game data size
I move it to micro sd using directory bind

just unmount micro sd before wipe using dialer
