Since this morning I decided to find a way to bypass inabilty to set MMS properties.
When I'll completly figure how to modify this settings I will develop an application where you will be able to put all the settings to set correctly the MMS APN.
So, I've started to investigate on my phone this morning, and I already found that.
It seems profiles are stocked in HKCU\Software\Microsoft\ShortMsg\MMS\Profiles\
Active profile is set as String in that key : HKCU\Software\Microsoft\ShortMsg\MMS\Active
Inside this Key, there is a Key for each profiles saved.
For my case, there is a key called "ORG-FR-APP". Inside this key, I can found this value :
TO-NAPID : String (Default Value = MMSAPN in my case)
TO-PROXY : String (Default Value = MMSPROXY in my case)
ADDR : String (Default value = http://mms.orange.fr in my case)
MS : DWORD (Default Value is 300).
I decide to modify value in registry trough MFG and I finally got that :
Before : http://attachments.xda-developers.co...1&d=1328002843
After : http://attachments.xda-developers.co...1&d=1328002843
The TO-NAPID and the TO-PROXY value seems to be linked to something I can see in "View config XML" but I don't know where I can edit them.
In deed, If I can edit them, the problem will be completely solved.
Here, the two screenshots which made me believe that the TO-NAPID and the TO-PROXY value are linked to something else in the file :
If someone know how to modify the set of values for NAPDEF and PXLOGICAL, I'm ready to do the software .
It's inside a XML File, somewhere in the phone.
I'll posting here if something new happens.
