[App] SpyCam - use your Mango phone as a hidden camera!

Hi,
I just want to share my app with community - the app is called SpyCam and it's pretty simple - you can use it for taking pictures using the main camera in predefined interval. The pictures are then saved into Saved pictures folder in Pictures Hub. But what is so unique on this app - it works under lockscreen - that's right, you start the photo shooting, press the on/off button to turn off the screen, plant is somewhere and let it take photos secretly
Note the app must be in foreground when locking using the on/off button to take pictures under lockscreen, it can't work in background.

I tried to put it on Marketplace, but it failed two times because "it appears that this application promotes spying". According to the certification guy it's not allowed in certain countries to have such app. Strangely there is lot of similar apps in MP for recording sound under lockscreen, so I don't know where is the problem.
I had big plans with this app, because the idea of taking pictures under lockscreen is quite tempting, but with the fail during cert process I don't have strength to develop it further. (Skyrim is more important right now I got even somewhere my technology demo based on SpyCam for storing taken pictures on SkyDrive, so it basically works as a live webcam - you can watch what's going on in front of the phone on Internet, but it's not stable enough for general release.

Feel free to use it under condition you wont try to publish similar app on marketplace Let me know, how it works. Note although it's not 100% stable, it should just work most of the time. I'm using there a bit of thread magic to handle all that PhotoCamera callbacks and async calls for taking photos and storing them, so nothing is guaranteed

And one more thing, you just need Mango and regular dev unlock. Interop unlock is not necessary Tested on HTC HD7

Don't hesitate to share it using Twitter or other media

Edit: uploaded two screenshots
Also my second try in MP used different name for the app: 'myCam', but they rejected it with the same message

Edit: This app does NOT work on WP8 as I have just discovered, it even causes freeze or random reboot!

Under lockscreen

You need to check the "run under lockscreen" option in settings and then restart the app (press Back button in the main screen and start is again).
Then start the shooting (optionally wait for the first pic to be sure), and then press the on/off button. Now it should take photos in selected time interval.
Note the app must be in foreground when locking using the on/off button to take pictures under lockscreen, it can't work in background.
If you have selected 5s interval wait about 20s and then press On/Off button again, unlock the screen and if everything worked as expected there should be new 3 or 4 pictures
