OMG... 
y not @ 512 ram .... ==

if compare to galaxy ace to samsung vibrant which one should i go for ?

Well, try the Milestone, its a FWVGA (480x854) android with only 256MB RAM. 

I can say although it has even less RAM than the Ace, it runs quite fine. Only thing is heavy multitasking is obviously not recommended. 

sure vibrant....

but the price....

i m a newbie with android... 

I got my unit yesterday from jason/moon. all the way from klang to kepong to grab the last black unit of the day

very satisfied with the phone. I got this ace and LG O1 in hand now.
I love both of them, but at some part I love the Ace a little more.

Ace pro's:
like the camera(5MP with flash),
the screen size(3.5"),
sound/audio reproduction,
android 2.2.1 out of the box,

con's:
speaker placement at the back( I prefer at the front like LG O1),
278MB ram (should make it 512MB min much like LG O1),
shining crome part at the side of the phone, looks cheap and fingerprint magnet( I prefer the crome part at LG O1),
lack of full flash 10 on browser,
old version of google aps out of the box, Market, Map all old version (can be upgraded through market),

I thought out of the box is froyo 2.2 only?? Then 2.2.1 can root??

this SG ace can update to android 2.3(gingerbread) ??
and the colour just black and white for back oni
*ask for my sis~

Yea only got black and white color available. hehe. about the 2.3 i not sure. android newbie

if compare to galaxy ace to samsung vibrant which one should i go for ?

not suitable to compare both phone.. coz both phone not at the same level..
samsung vibrant specs is like samsung galaxy S.. which is should categorize as high-end phone..

if ur budget below RM1k.. for low-end phone.. Galaxy Ace specs is better than other low-end phone..
if ur budget more than RM1k.. than u should not look at Galaxy Ace coz mid-end phone specs should be more better..

Anyone know Galaxy Ace SP and casing is available?

thanks

Any ways to disable data? Just wan to call and sms

nop,
they are not available yet.
I use custom SP that cover the screen area, and use pouch to cover the whole body inside my pocket

go setting > wireless and network > mobile network > off data enabled and data roaming
and tick oni use only 2g network
hope it helps

Anyone here succeed in rooting this phone??

I see  I see  , thanks for the info .
