App not running correctly on Ipod 3g

I'm having problems running my app on my Ipod. I've tested it on an iphone 3gs device which works just fine. It also works fine in the simulator. On the ipod DEVICE however the UI is messed up, and doesn't show anything but an empty menu and the no image sign.. I'm also getting the following warning in the debugger console: warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/usr/lib/info/dns.so (file not found). I'm getting this warning when running on both the Ipod and Iphone, but the app still runs smoothly on the Iphone. Does this mean that the app's interface somehow is not supported by the Ipod 3g? This would be nice to know when submitting to app store =P both my ipod and iphone is up to date with the latest iOS, and so is my SDK : ) I've also tried re-installing SDK, re-setting my device etc etc. In advance, thanks! Looking forward to v1,5! Keep up the good work!

(EDIT:) Okay, I've seem to found part of the cause. When i turned on wifi on my ipod while installing from xcode, everything worked just fine(?).. But my custom html pages are not working as they should. In my app I have several sub menus with custom html pages.. some of them loads and some of them just gives me a black screen.(...) And now, as I'm writing this, suddenly everything works fine again even without 3g/wifi. This is really frustrating.. I can't publish my app with such inconsistent behaviour :(

For sure, it doesn't make any sense to publish an app until you understand how it works, etc. The behavior your describing could be caused by lots of things. The most significant this is the WiFi connection. The app will need to be WiFi connected before it will do anything. After it downloads all of it's data, it does NOT need to be WiFi connected unless it's using data from the web. This also means that any changes you make on your control panel, after instsalling your app on your device, will need to be updated - making WiFi required. Use the control panel to make changes, use the Refresh button in the app to see those changes. Thounsands and thousands of iPod's are running apps created on this site. This means that whatever the difficulty you are having can be figured out. It's a matter of your taking the time to understand exactly what the relationship between your control panel and your installed app is. Hope this helps.

Also, it's impossible to know why your HTML is not displaying right. Writing clean, valid, HTML is a skill and does take time to master. If the HTML is loaded on the phone, and it's valid, it will render as expected.

Thanks for quick reply (as always)! I figured it had to have something to do with the WiFi. I tried switching on Wifi after installing it from Xcode, play around with the app for a while, then turn the wifi off again. Works like a charm. This seems to have been the problem with the html pages as well; the content simply hadn't made it's way to the device yet.. I did not realize that the app somehow had to connect with buzztouch to download content. Thanks for the enlightment on that matter! =)
