Xperia Mini/pro :: SK17i - Mango - Front Camera (option) Missing?

So, I've always been on the stock GB rom it shipped with and had no issues. I decide to update to ICS but since the update doesn't show up in PC companion or Update Service or OTA, I get flashtool and the stock .431 ftf and flash my mini pro (SI 1249-0751) to ICS (and also plug in a fresh new 32GB microSDHC card to celebrate). A bit laggy, crashes of the contact viewer when searching throught the dialpad, but that's okay, I can use a different launcher (Zeam) and dialer app (Dialer One).But when I open the camera app and try to take a picture with the front camera ...... there's no option. It's gone.

Another camera app, no front camera.Skype recognises only the rear camera. No front camera.I open the service menu (*#*#SERVICE#*#* i.e *#*#7378423#*#*) and test the secondary camera, and it says "This device does not support the function". The primary works fine. All other supported features work fine. Light sensor (next to the front cam) responds too. (But the Proximity switch doesn't. Not sure if it should. Perhaps that could hint at a hardware problem with the connections from the bottom half to the top slider part.)

I scout the forums and find that there's some some strange relationship between the SD card and the front camera for the Ray (or some other device) . With the old SD card, still no luck.I downgrade to GB. Still not working. Front cam missing.I unlock the bootloader and install a custom rom (CyanogenMod 9.0.0 Stable mango).Still not working. Front cam missing.I reinstall GB, relock the bootloader in the hope of an OTA update and do finally get one (to ICS). I update it. Still not working. Front cam missing.I don't think it's (gulp) hardware. There hasn't been any drop onto a hard surface.
