Hello everyone, I did test the build on the above date and these are the results:

- IPod 3G the app starts but does not respond to the audio of the headset microphone (working, tested with the vocal memo).
- IPhone 3G app crashes immediately after the appearance of the spreadsheet, making it impossible to even see the main menu
- On the simulator app is functioning normally and responds to audio.

i don't know even where to point my eye on the code...some adivice to find the error?
thanks

The crash log from your iPhone should give you a good place to start. Unless it's been changed since I last used Xcode (which was quite a while ago!), you should be able to get the crash log in the organizer window while the iPhone is plugged into your Mac. If fixing that problem doesn't help your app on the iPod, you'll probably need to do some debugging with printf/gdb to find the root of the problem.

thanks a lot, i'll try

i have found that was a problem of memory, now the app works without crashing.
now.....the app uses a mic, in simulator the mic detect sounds, in device the mic doesn't detect anything!

the crash was a memory problem, now i have another strange thing:
in simulator the app respond at sound from mic, in device when i speak into the mic, no sound detection...
no error in debugger on any NSLog i have putted.
i don't know how to recognize where is the problem...
if anyone has ian idea would be great...
thanks
