Apparently Google admitted to breaking some of Apple’s rules to have the latest Google Mobile app available.  A Google Spokesman confirmed Google did use undocumented APIs (Application Programming Interfaces) in order to use the iPhone’s proximity sensor. I have yet to use this app, I think its necessary at this point, but it seems the proximity sensor is used to prompt a verbal search.

Details of where Apple and Google now stand are still a bit unclear. In the past, using undocumented API’s would violate Apple’s. As of late more app developers are seen using similar techniques. It’s unknown whether Google snuck a fast one by Apple, which some have alluded to, while some believe Apple may have given Google a bit more freedoms here. I’m sure there’s a clause in the agreement which states Apple, regardless of what this agreement states, holds final judgment and authority regarding approval or disapproval of an app. [cnet]
