Hi, I plan to flash my s2 from GB to ICS. I will do the full wipe for it

Btw as I know, wipe data wont erase the data in internal memory.
Since the internal memory got a lot of data file and apps folder from previous GB rom, will it affect the ICS stability? or I hv to format it in Setting -> Storage after I flash the ICS rom?

oo... thanks for ur reply
previously i thought wipe data just wipe the 2GB ROM storage, not include the apps data/folder in internal storage.

I hear ICS 4.0.4 got lot of improvement and bug fix for ICS.
but i wonder y some of the development like Thebyani ROM and WanamLite still stick with 4.0.3 in their recent update.
Is it actually 4.0.3 more stable than 4.0.4?

coz now i'm still no idea flash which ICS Rom better...

sorry i got some question again...><

by default all my contact are save in my phone local storage.but if I sync it with google mail, all my local phone contact will become empty.
is there anyway to get back my contact from google mail to save in my local phone?

and before i flash to ICS from GB
for whole ROM backup - nandroid
for apps data backup - Titanum backup
for contact backup - sync with google mail, kies
for SMS backup - Mybackup Pro, kies

is it correct? or got better way to backup and restore? especially contact and SMS

Thank you
