you can try update it via OTA, which go setting > about phone > software update
to check your firmware,
setting > about phone > scroll to most bottom > look for build number

If I check for update using phone, and it always said no new update wor. So I thought I'm on the test firmware until yesterday I connect to my computer using kies for the first time, kies told me I there is new update available. However, if I check using my phone, and it still said no new update. My current build is IMM76D.I9300XXBLG1

OTA Update Center – Someone (Finally) Got it Right
POSTED AUGUST 8, 2012 AT 7:30 PM BY FALLENWRITER

The dichotomy between custom ROM developers and OEMs has always been interesting. In the early days, developers focused on the major issues that plagued Android: smoothing out the UI, overclocking, memory management, etc. With many of these issues now resolved, developers have begun to focus on adding features that will enhance the user experience and take Android development to the next level. One such feature is the ability for custom ROM developers to seamlessly push OTA (Over The Air) updates to their users.

For a dev to do OTA updates currently, he (or she) would need to have his own hosting infrastructure in place. What the crew with OTA Update Center has done is centralize the entire process into a free, easy to use service that takes the legwork out of the equation. The result is a centralized system that features:

Add and remove OTA Updates in a centralised database.
Check for updates on boot of devices.
Check for updates manually when the person wants to.
Download the rom and flash it directly.
Download the rom without flashing.
Wipe data and or cache/dalvik before flashing the update.

Did I mention that the crew behind this service does not charge for it? So what are you waiting for? If you’re a ROM developer looking to take your game to the next level, head on over to the original thread or to the OTA Update Center homepage. Of course this wouldn’t be possible without the amazing team behind the service, so if you’re interested in contributing have a look at their credits page.

Any high capicity batter for s3 ?

Y? I still happy with stock rom lor.

Someone back in v14/15 posted a 4400 capacity battery from ebay with its own custom back casing as it is too big. You can try but as far as i can see no one from here dare to try it back then. I am on my phone atm so i cant search for it.

just got SGS3 for my wife bday. but totally forgot about the micro sim. dem! tomorrow only can go to celcom..ayarrkkk!

he not saying batt packs, he is talking battery, which is = "take out cover and put in" battery, not the external battery

if im not wrong, u can cut ur sim from the shop where u buy the phone..

i buy it from sunnychai99. cod at sunway pyramid. where got potong sim card. and i totally forgot about it..
