Hello again, we want to make a survey. For this we made a j2me application which should be installed on several nokia mobiles which we want to give out to the participants. The problem is now that we don't want that they can close our program and use all the other functions of the mobile(like phoning etc.). So we changed the program this way that you need to type in a pin if you choose the "quit"-Button in the program. That works fine ... but if the participant simply presses the replace key (I mean the hang up key with the picture of an red telephone receiver) the program stops immediately (There are also 2 or 3 other keys like the photo key, ..).
What can I do that this never happens? Is it generally possible? If not, are there other devices which I could use?
Actually we use an 6210 Navigator ...
Thx a lot
