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

This has been proven no longer working, ur last resorts will be
1) switch/port over to other SP
2) Jailbreak ur baby as i just did,now im no longer worry of the stupid data charges ^^

iPhone Generation : 3GS
Unlocked? No. Officially unlocked from Maxis
Current Firmware : 3.1.2
Current network : Maxis
iTunes Version : 9.0.2
PC/MAC : PC
Jailbreaking software : blackra1n
Problem Encountered : "Internet Tethering" option is missing
Steps Taken So Far : Reboot the device and tried other SIM
Screenshot of Problem(if applicable) :
Other Information/Remarks :

"Internet Tethering" option has always been there and turned off after I JB'ed my iPhone with blackra1n. This afternoon, I turned it on and then selected "USB" as connection method. After that, I'm not able to see "Internet Tethering" option anymore.

I've tried rebooting the device and using other SIM card but it still not there.

Any idea? Restore and re-JB would be my last choice..

Thank you..

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.

Ok, I got it, and tested it, push is the culprit, push must be disabled if u dun wan data roaming in your iPhone

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

and for the cellular data network menu, please check the thread carrier logo in the forum

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.

If u have read thru the rest of the iphone related threads over here,fake profile is no longer useful, its proven not blocking ur 3G connection anymore. Newer manufactured iphone (just like mine) is no longer having the APN setting,ur sis set is gotta b an older set.
hmmmm to me PUSH - the word itself sounds as if it will make sure u get ur data received eventhough ur device is inactive, so u did the rite choice for disabling it rite now.

the cellular data network tab is still there,u need to download custom telco logo to enable it
