Thanks for the suggestion waveweaver, pardon this question from an inexperienced (<2 week android, <1 week root experience) user but when you mention CWM recovery, i assume it has already been installed into my phone when i rooted it even though i can only see CWM and SuperSU icon in my apps. I assume i can enter the recovery either via the CWM manager or the triple button combination on phone. Does the choice of backup appear in the recovery mode or is it an apk app that i activate similar to all programs e.g. ROM manager and it will self boot and self backup after that?
Strangely when i try to use the CWM, it says "This version of CWM Manager should be used with CF-CWM v1.1 or newer. It appears you are running a different recovery. Various features have been disabled". Umm, i am in need of a dictionary to explain this. Does this mean i have to re-flash again? I used the Odin method of rooting my phone last week.

Thanks again.

restart will get rid of it

Many thanks to both of you for your suggestions. Manage to finally get it to recovery mode to backup my phone. Not sure what was wrong but i failed even with flashing the CWM recovery 5.5.0.4 - "v1.5" by itself. So decided to do the whole shebang CF-Root 6.4, that reset the whole thing and now it works, even the CWM manager. Yea!   

My previous attempt to root was with CF-Root 6.1, maybe that version caused some gremlins in my S3. Not sure...

Anyhow, all is well. Till JB anyway. Haha. 

ya indeed.. got 1 window update regarding samsung 1.

@SteadyPana u should check the window update as well.

downloading and flashing now...  

iz wanamlite good?
never try b4...stable or not?

Ya, already flashed Wanamlite Deodexed XXDLI1, 3rd party keyboard no issue unlike previous leaked XXDLH9

i will do it with http://forum.xda-developers.com/showthread.php?t=1772234
my memory wanna full already   

this mod will increase internal storage space??  

so how about my data in sd card now? must move it 1st? 

forget already

waiting gadgetcheck build the latest JB leaked

after some reading, the crashes for the latest jb leak on wanamlite is suspected to do with the touchwiz interface.

before some users using launchers, and other roms like omega, which uses the same jelly bean leak base, aren't having this freezing issue :/ hm. .....

Yeap..factory reset..use titanium backup only..for some apps..
Er..but the issues is jellybean issue..every ics to jellybean got the same problem..no pic no music..media scanner problem

the question though is the hidden costs .....

For umobile when you exceed your monthly allotted cap, you don't get charged extra. your download/upload speed however get throttled, but at least you aren't getting charged extra.

For maxis they will charge you for exceeding your cap i believe. Which is why i don't like using Maxis for Data plan 
Be very wary of Hidden costs especially when it comes to internet mobile data plans as you can easily exceed bandwidth caps especially when streaming video, music, torrent and other bandwidth intensive activities.

I believe is Unifi fault, because each time i open/re-flash LYN webpage & XDA webpage it took few second to complete
