it's called reverse engineering though. it's much easier to use reverse ios code than that weirdass dex format though imho

You can convert .dex files back to .class files, and then use a java decompiler. Not all functions will be properly decompiled but overall it's still quite good. Knowing this, reversing Android apps is actually a lot easier.

Really? I've done it once or twice, not hard at all with smali: http://code.google.com/p/smali/
