Does anyone from Saudi Arabia have the same experience as mine?

Just recently bought my N900. I was using it for the past two weeks with an STC SIM (which still connects to the good ol' 2G network). I have downloaded the settings for the MMS and Internet connections and was not having any problems except it can't connect to the 3G network because of my old SIM.

And today I switched to Mobily SIM. Then I downloaded the settings. But unfortunately something happened. When my operator sent the settings, it overwrites the first setting that arrived. i.e. the setting for the MMS/WAP arrived first and was saved. and then the settings for the Internet /Streaming arrived next. After receiving and saving these settings, I should have 4 connections on my list. But I only got the last setting that came or the last saved settings.

Actually, I can install the settings manually using fAPN, but I hope someone can figure out this one so it would be much easier. I think this pertains on how the operators send their settings to different phones.
