IPhone or Android SDK?

Hi, I'm a junior developer more on Java programming language particularly on web. My boss asked me if I can develop POS application for mobile. He gave me options, iPhone and Android. I read some overviews and features both SDK is capable. Would like to know what would be the easiest SDK to use which includes the familiarity, coding, functionality and resources. Thanks|||Objective-C and the Cocoa framework are fun to work with, but only once you've got your head around a lot of Apple intricacies. I haven't used the Android API, but I think it's likely to be better from my previous experience of Google APIs.|||just the same... OOP in C++
