Did you read this?

http://forum.lowyat.net/topic/752226

I may not understand what u want me to check.

But i lost the 'Cellular Data Network' under settings>Genaral>Network, not the logo.

I try the same iPhone with my DiGi sim card, the 'Cellular Data Network' is there.

Wired why my maxis simcard can not get the 'Cellular Data Network'??

setting the logo, not only make the logo visible, but also make the "Cellular Data Network" settings visible.

Well, i have gone thru this once.
When booting up, i have about 20-30 seconds to see my data using iPhone Browser, and i use that time frame to backup my contacts and SMS.

I am affraid that's all you can backup with that given time.

There might be other ways, but thats the only one i know.

I got the 'Cellular Data Network'!!

But the MMS function still can not works.

This is my setting:

APN: unet
Username maxis
Password: wap
MMSC: 80
MMS Proxy: 202.075.133.049
MMS Max Msg Size:10
MMS UA Prof URL: http://172.16.74.100:10021/mmsc

Anything wrong??

Blank out the 'MMS UA Prof URL:'?

I just called Maxis and they said it is activated. I tried using the gprs to get the 'weather' .... and it works.

Hi all...

I just install the activatemms2g from a china website and is pxl file but the carrier change to "china mobile 4.0" previously was "maxis 4.0", I try to send mms but fail, I try the setting in this thread but also fail, do I need to change the carrier bundle"ipcc" ? then only config the setting again? Help pls....

1) why did u install from the china website? did u not have cydia installed on your phone?
