Using the Titanium platform ID

Hi,

 I'm using Titanium.Platform.id in my application and researched related to this. 

 Many says accessing UDID rejected their application during upload to app store..

 I'm using two modules also. One is Matt Tuttle's Google Analytics and Another one is Ti.imagefactory.  

 are UDID and Titanium.Platform.id related? If i use this Titanium.Platform.id, will apple reject my app?

 please suggest me a good solution..
