i decided to go to maxis service centre at taman tun..after talking to a nice lady there.she mentioned to me, whenever any wireless connection is low, even the signals on the iphne shows 2 bar, it will automatically switch n connect to 3g service to surf the net smoothly. it must be 3 full bar for you not being charged using the wireless.. then i ask her, how bout if i have disconnected the 3g service (remember wat i did on the previous month) n she replied an answer that shocked to me mentioning that, even though u have dscnncted the 3g service, because the phone is 'so' intelligent, it will automatically enable the 3g that has been disconnected and connect to net through the service..so disconnecting ur 3g service is not a solution.thats y we have data package for contract phne (cehh). By the way, i cant see any termination of 3g service for ur accounts since may 2008 (damn you 1st maxis guy. he didnt terminate the 3g)...

3g usage will increase even those u off the edge/3g but it only increase very very little....

i'm on unlimited plan cause 3gb not even enough cause i'm heave user.... in a week i can used up to 4gb that stated in iphone but as we not iphone usage r not accurate....

so for those who din use unlimited plan pls bear in mind always off ur 3g or edge, non-jailbreak iphone user have to becareful...

No la bro mine oredi blacklist my 3g service n oni wifi at home n office... No data being charged to me....dont ask for disable but ask for blaxklist

@kakikukaku,
tnsai oredi answered ur question.  Put in a fake APN or a fake profile to disable data services.

@Mackiddo,
When on earth are U?  U have 30GB limit of data usage on your mobile ?! That certainly is a huge amount!

. even if so.. I got  money, I like, I buy the Iphone.. what's it to you??

u use the data service right after u get the phone and insert the sim card?

i get on friday 8pm and the staff told me my i data plan 1 only activated after 12 pm on saturday ... before 12pm is pay per use, which is 1Mb = RM10

now...u pay 88...u still can get connect(they wont cut), again threshold 3GB, once u exceed, speed remains...but u now pay for all the extra u used after 3GB

Guys, the earlier method didn't work. The data usage is still increasing even I had changed all the apn settings inclusive of the mms as well.
What else is there to do now? Can someone pls guide me?

Perhaps if that's the case, u should feedback to Steve...telling him to release a strip-down version of iphone....
iPhone nano....no data, GSM only, all people need is app/game that don access internet, and the fancy touchscreen

There's already 1mb data download in 1 day. It'll be around RM10 I think for 1MB. I really need help now. Nobody is having the same problem as I am? Everybody is with data plans? Will jailbreak to install sbsettings help solve this problem?
I just wonder why after changing the apn settings, it is still possible for the phone to connect..

did u guys check your carier version...? setting>general>about , as mentioned in a thread, that apn thingy setting only work with Maxis 4.0....mine was 4.0 before, just now i checked mine already become 5.0, so the apn thing doesn't work anymore...now im trying to restore to factory setting and see how thinhs going

That's what u thought. After changing almost everything I could think of, the data is still downloading. The apn settings doesn't change even if u set it to some fake apn. Something else needs to be done which i'm not sure what that is right now.

done restoring to factory settings, the carrier version remains at 5.0, great and i have no idea how already

any other alternate way now?

if you have the dough to get an iPhone might as well get a data plan. Digi is having a special promo, RM40 and Maxis came out with a 500MB data plan @ RM58. that's around rm2 a day! cheap!

data package completes your iPhone! power sial!

Got one question here. I already disable all my 3G, Data Roaming and Location Services.

So far, from day 1 until last month, my phone bill just like usual, i just paid for all the calls and smses.

But this month, i found out there is another charges due to internet data usage which cost me around RM170.

FYI, i bought my iphone from Maxis thru prepaid package on end of JUL-09

Anyone face this problem before? Is there any problem with my phone?

turn off ur data roaming ?

setting>general>network> data roaming [off]

im just beginner of iphone.. correct me if im wrong. 

hey guys... i just updated my iphone 3g from 3.0 to 3.1.2 andjailbreak+ unlocked it with blackrain. the problem is i cant seem to disable the edge or data with iphonenodata.com or unlockit.co.nz. i've even tried with sbsettings but i still have data charges. i'm using hotlink prepaid and my credits are just running out every second!!! please help!!! thanks!

hey guys..ive encounter a problem.
Before yesterday, my iphone is unable to online unless i use wifi. the edge/3g doesnt work. However, since yesterday i can online even though i switch off my wifi. Im wondering why does this happen?
And yea, after i switch off all the push/notification thingy, the data still leaking i guess..from 900kb+ till this morning 2mb @@
may i know what happen?
im not under any value plan anyway. i dint sign up any of them. thx~

Got a question... I'm using idata 2 now.. which is 500 mb per month...
I bought my phone at 28 of Dec.... So the data plan starts on that day itself right?

Are you sure it's not increasing from Wi-Fi?

Sorry if this has been covered, does digi support tethering?? Now looking at jumping ship from maxis to digi

Just wanna share.

I been an iphone user for about 6 months now. Not having the problem until a weeks ago when I notice my prepaid goes down the drain in a jiffy. Imagine RM100 in a day!! wtf. Why only after 6 month this thing happened? To me a smartphone should do what the user wants instead of what the telco wants ie your money... Just my 2 cent.

Now I tried SB and fakeAPN after reading this thread. Don't know if it gonna work but I'll keep my fingers crossed!

don get it wrong, 3G is the speed u get, not the amount of data
it get ur data download faster....onli if u access a lot data....
so ur key is not to turn on 3G more (u can always on, or turn on onli when u need it), but to use data access more
