Air SDK No Longer allowing PHP>MySQL Communication?

I've been designing .swfs/games/Apps for a long long time, and one of the fundamental aspects for my Apps (and a lot of Apps) is access to a database. Up until SDK 17, I've been able to send/receive data through Flash/Animate -> PHP -> MySQL and back again no problem. Makes for some cool stuff. Now, nothing.

I can still obviously do this when exporting a .swf alone, so I'm assuming it has nothing to do with Flash/Animate itself, but if I use any SDK from v18 on to export to an iPhone, nothing happens. I cannot tell if data is not being sent or received or whatever, but I do know if I export a .swf = perfect. If I export via SDK to a device? Nothing. So what's up?

No, my phone is not in airplane mode. Yes, it has a stable internet connection. Until this is fixed, I'm stuck using SDK 17. This is now becoming a problem as other extensions I use are starting to require newer SDKs.

Any chance of adding this back to the SDK, Adobe? I'd like to keep using your products.
