Memory problems with my iPhone App

What kind of answer are you looking for without posting any source code? The size of your files doesn't matter.

Do you have a leak, or are you just declaring something that takes up a lot of RAM, such as a UIWebview?

 

Profile allocations then sort by size.

 

Have u tried using Command shift B? It's a command to let the analyzer do his work to check for immediate mem leaks.
Second of all, run your target on your device via Instruments (crap since Lion).
And check where you're allocations are, which aren't getting released.

 

Here's a little tutorial: link.
