Learning How To Test Mobile Device Applications (Part 3) - BlackBerry

In this HOWTO series, we've covered two popular mobile device platforms, webOS and Android, in these articles:

Learning How To Test Mobile Device Applications (Part 1) - Palm webOS
Learning How To Test Mobile Device Applications (Part 2) - Android

Today we'll look at BlackBerry. As we've stated in previous articles, our goal is learn enough from developing simple apps on each platform so that we have a better understanding of the platform as testers. And we want to accomplish this without having to buy each mobile device or any development software. Fortunately, developer offerings from RIM meet these requirements, albeit with less hipness than webOS and Android.

iPhone App Project Managers - How Did You Test Your App?

iPhone application development is exploding (How Hot Is The iPhone Application Development Market?). And users are demanding better quality - no longer is it acceptable for an iPhone app to crash unexpectedly with the explanation that apps crash every so often because of the iPhone OS. Moreover, with more-and-more iPhone and iPod touch models to choose from, developers face a compatibility testing challenge. So how are project managers testing their iPhone apps?

We'd like to hear from iPhone application developers and managers who have navigated their way onto the App Store and can share with us the problems they faced in testing their apps, as well as tips and recommendations.
