Hi, I'm guessing this has been covered before, but I can't seem to find it in the thread. Would appreciate it if anybody could point me in the right direction.

iPhone Generation : 3GS
Unlocked? (or Part Number): Artifically unlocked (Part Number MC145C)
Current Firmware : 3.1.2
Current network: Maxis
iTunes Version : 9.0
PC/MAC : Mac
Jailbreaking software : blackra1n
Problem Encountered : Cannot receive or send MMS after a friend tried sending an MMS to my phone.
Steps Taken So Far :
1) Googled for enabling MMS. Support says to enable MMS, go to Settings > About > Network > Cellular Data Network
2) Realized that my phone doesn't have the Cellular Data Network tab
3) Googled on how to enable back said tab. Found this thread: http://forum.lowyat.net/topic/868281/+10

Other Information/Remarks :
What I wanted to know is since my phone is not a phone bought from Maxis itself, would restoring to factory settings solve the problem (enabling back the Cellular Data Network tab)? My sister had a Maxis unit (3GS, running on 3.1.2 and JB by blackra1n too), and while the carrier is Maxis 5.0 (same as mine), her unit has the Cellular Data Network tab. Which made me a little curious why is it so, when the thread (link above) said that only Maxis 4.0 carriers are enabled for it. And is this (no Cellular Data Network tab) only applicable to artificially unlocked phones?

Also, from that thread, I got a link for enabling the tab (http://forum.lowyat.net/topic/752226), but after reading through the thread, it seems like it's more on having a customized logo carrier than to enable MMS. Any other explanations or linking to other threads will be much appreciated

Okay, thanks...I will try that when I get home. I went looking at Apple's Support pages for iPhone, and there was no support page for the Cellular Data Network tab. So, maybe this tab is only applicable for Maxis units?

Added on January 12, 2010, 3:13 pmThanks for the info! I tried step 1 many times. Didn't work.

Don't know if it's the network problem, because my signals are good where I am. But I will try with the maxis website. I don't know if I should give a call to the maxis center, as my iPhone is not a Maxis unit...not sure if they will take any action on it. Worst case scenario, forgo MMS... Not that I use it a lot, but it sometimes is a good feature for last min. photo sending. Thanks again!

Just a question...did you use the iPhone_3.1_Maxis_my.ipcc file or the Original_iPhone_3.1_Maxis_my.ipcc file? I'm a little confused as to which one to use. What's the difference between the two?

Thanks. I will try with the IPCC file first, and if it's not workable, I'll call Maxis and see. Appreciate it I tried the Maxis website...all I got was "Sorry, Phone Model is not Configurable. It appears that there’s no automatic configuration or manual configuration guide for your Apple iPhone 3GS."

Okay, thanks very much! I will try that out.
