This is very much a maxis issue now.

Last time when I first got my IP5(End of last year) I do not have this prob. That was with iOS 6.0 firmware.
Then after I upgraded to 6.1, the prob started. So obviously I would think this is due to the firmware.

Earlier today, I just got my replacement set with iOS 6.0.2 and guess what, this 3G bug is there.
So the conclusion is - its not the firmware but Maxis.
I asked the staff and they themselves admitted its not due to the firmware and they said Maxis is looking into it.
We'll see

Finally i found a way to force 3G only on my iphone5. I installed auto 3G from cydia, source from ihacksrepo.com
Now i can enjoy 3G connectivity without a problem. So much happier wit my ip5 now.

from all the problems they have now,i think maxis is the main problem now,
my fren who use digi ,u mobile(me) got no problem switching from E to 3G
maybe it is time to change carrier? 

no need such drastic action, just downgrade to iphone 4S cukup. 

Apparently it does. Else they won't be gazillions Note users out there

Old pipu , need something big to see screen clearly even without specs.

Frankly. I have android phone also. and they share same size SIM. But my SIM always in my 4S. because my HTC facebook app damn suck. thats all it takes.

I would still stick to my trusty iphone 5 thank you

Would rather bring along my Mini if I need a bigger screen along the way
Don't like to put a purse-like phone in my jeans.

Err. S4 and S3 is having the same dimension. Just the difference in the bezel only so the screen area is bigger for S4

Note - sorry, off topic d

I love ipad mini size however i'll wait for the retina display version, i believe it will come soon.

izit about the batch thingy? first batch got some problem,like S3 got sudden death issue like that? 

i think its maxis problem, now im using digi, so far no problem, no need tweak here there to get 3G.

It is maxis issue.. Previous firmware was alright.. Then update to the version 6.1.. All haywire d the connection... 4 of my fren having this issue.. All maxis user.. All happen right after the update of 6.1..

can claim back to maxis since this is their problem? keke

Nope.. Im not.. Since the first day bought.. Dine JB yet.. And it is sure maxis issue..

I just bought my iPhone 5 last friday from celcom. My iPhone uses a proper nano sim from celcom, while my one x uses a micro sim cut from a Celcom normal sim. Enabled 3G on settings in iPhone but this happened. Rebooted/airplane mode multiple times but to no avail. Any tips?

P/S: signal not strong enuf is BS coz my one x is riding on HSDPA all the time. Don't even have to force it in the settings. This is the only thing thats stopping me from enjoying my iPhone as a daily driver so if you have any tips, do share.

I googled about Auto3G and from what i can understand, it turns off 3G when you lock your phone to conserve battery life. Can we actually use it to force iPhone to connect to 3G all the time? Like how android can force the modem to connect to 3G/HSDPA?

I'm on iOS 6.1 now. Can i grab the 6.1.2 update somewhere and use it to update my iPhone before i jailbreak? Because 6.1.3 is out and no jb for it

BTW do you happen to know any good theme sites? So far only Jaku catches my eye. The last apple product i JB'd was an ipod 2G so its been a very long time. No idea what happened to the theming scene (long live Dulce theme)

i have the repo too . ill download it now , just wanted to make sure 

For those who are not jailbreaker's. maybe you want to try these method.

Go to Settings
1. Carrier - used manual selection (select your service provider)
2. General>Cellular - Always switch on 3g. ONLY switch off cellular. DO NOT need to switch off 3g selection if you doesn't need 3g or you want to safe battery power.

Mine works well now.
