iPhone 4S and iPad Mini iOS 7.03 -

I created a map app and when I click on the tab with the map my app crashes, it works in simulator and on iPhone 5 with iOS 7.03 just not on those types of devices? I get

Exception Type: EXC_BAD_ACCESS (SIGSEGV)

Exception Subtype: KERN_INVALID_ADDRESS at 0x00000000

I have looked at the code and can't find the error and I have tried it on other devices like the iPhone 5 with 7.03.

I have updated xcode to 5.01 and still get the same error.

the mapp allows the user to enter in the Lat/Long of a friend and then maps it. If I launch the map without entering the LAT/Long it will launch but when I go to add the pin annotations it crahses. When I step through the code it does not crash at any point of adding the annotations, it excutes the code and when it finsihes is when it crahses.
