There is a 10MB limit on 3G app store distribution; anything over that will be wifi only.
Memory management is handled via a set of rules that are basically if you create it you are responsible to release it. If you borrow it you must not release it. Similar to malloc/free and new/delete in c/c++. It is a level of abstraction higher though. You are dealing with retain counts and autorelease pools. A memory leak in an application can crash a phone with limited memory fairly quickly.
