LocationAwarenessoniPhone

LocationAwarenessoniPhone  Hack Cell id location into the iPhone and integrate with Yahoo! Zonetag (http://zonetag.research.yahoo.com//) 
Introduction
Zonetag makes it easy to get Location. http://developer.yahoo.com/yrb/zonetag/locatecell.html 
Details
Reverse engineer the FieldTest.app to get API calls that we need. 
Ok, finally managed to compile not crash after reverse engineering FieldTest.app but what does it do ;-)
