then you will miss the greater JB Iphone ever!  compare non jb iphone with jb iphone theme..sure cry laaa 

it doesnt matter..but for now i duwan JB first
now every minute my credit flying.. 

it just happen today..just top up RM30 ytd n now left RM5.. =.="

just sayin, my 3GS (maxis official) behaves better with JB. I can actually control HOW I want to use my data allocation. This way, I won't be helpless if my phone is leeching data without me knowing and Maxis will only say "it's an iPhone, get used to it."

I WON'T get used to it because on my previous i3G, with U Mobile prepaid, the cellular data NEVER moved unless I meant it to. and yes, that meant JB-ing, installing SBsettings, disabling Fetch for email and also watching what apps I install and what they do (ads, etc).

Battery life is still a day and a half - which is normal with regular use.

For the record, JB-ing isn't a criminal activity. It's like installing software on your windows to manage your processes/performance and customise your rig.

man even i installed both fake apn profile also can use cellular data...i need to fix this fast

or you could call up Maxis to disable 3G services

do you use sbsettings? Not really work for me.. Both 3g n edge off d, and installed profile at iphonenodata at the same time, do u turn on push?

when turn to sleep mode, the lcd is not shut down at all, i still can c it is under standby mode (black display after lock the phone), if we shut down the phone, u can c the lcd is no black display , im not sure this is normal or i press something wrongly, anyone can tell me what i 've pressed? lol.

only postpaid users can cancel the internet services,not available for prepaid users.
me myself facing this problem too.
what did you mean by push?
my problem is, previously i installed the profile from iphonenodata.com and the time everything was disabled. but after i went to singapore and came back last week,something wrong with the setting. phone will connect to GPRS directly if i accidentally tapped the safari w/o switching my wifi on thou my phone is using the disable-EDGE-GPRS-3G profile.
I would like to ask,why does is happen?

btw, i couldn't find the cellular column in my iphone while I could find it on my sis's phone.

I disabled 3G n EDGE in sbsettings, I do some little experiment. I enable push with disable 3G profile, when the phone is sleep, wifi will close temporary until u unlock it back on. When the phone is sleep, I think because mine is maxis iPhone? Even I use custom apn, but the iPhone still able to sent and received data. When I disable push, no more data transfer, done this few times, but IMO push really could eat up your credit when your iPhone is sleep,even u disabled edge and installed profile correct me if I were wrong
