Hi,

I am trying to execute different things depending on what os the users iPhone is using.

Currently I have the below, which says - "if the device is 3.1, post this message"

#ifdef __IPHONE_3_1

NSLog(@"this device is 3.1"); #endif

But, How can I get it to say - "If the device is 3.1 or higher, post this message" ?

Thank you very much.
