Memory Leak on iPhone device but not simulator

[slobbymon]

I have an unusual memory leak. On the simulator, there appears to be no leaks when loading my tables and custom cells from NIBs but when I run on the iphone device using leaks, it shows several leaks, mostly in custom cells that I load from NIBs.

Do these need to be handled differently on the device than on the simulator?

How do I dispose of them then?

Thanks!
