That was useful stevie, well done.
In answer to your question Censura, no, it's not a native feature, it's a CM10 addon feature that is massively desirable and I missed very much when I got this phone, which is why I have a stock ROM with the CM10 MMS.apk and this gets me the drop down features that you are missing. Feel free to PM me, and I will send you the APK. I took it from a standard CM10 nightly although I tried a couple of them before settling. All you need to do is drop it in your System apps folder and check permissions ofc. What I do suggest is backing up the original MMS.apk as I'm expecting OTA to fail with CM10's MMS.apk.
