Tired of worrying that your N70's slider might open in your pocket, starting the camera application? I found a way to disable this when I was mucking about on TaskSpy:
(This should also work in Feexplorer)
On the "processes" tab, I found a process called "CamServerCore", were I killed it. I closed the program and decided to open the slider and see what happend. The camera application didn't start. I was worried that the camera didn't work, so I opened it manually through the menu. It worked! Both cameras were working... closing the slider even closed the camera application.
Because I started the camera application, I thought the phone would reload the "CamServerCore" process. I opened the slider again, but it still didn't start the camera application. All it did was unlock the phone.
I'm not sure if this works with an N70 with a firmware version over v2xx though, or that I'm sure that phone the phone could crash. If you don't like going into the menu for the camera, you could set it as a shortcut on your main screen.
It's also a handy way to unlock your phone without the usual left key + * combo...
Some people might say "I don't want my phone to unlock while in my pocket when the slider opens!" I'm sure that could be easily solved too, same way as the camera application.
