Well, I have the old version of MemoryInfo and the System Activity Monitor app with free memory capabilities, but neither of them will work with the 4.0 beta. Anyone that used the 3.0 betas knows that the memory was a huge issue with leaks all over the place. I found MemoryInfo to be very valuable when using the 3.0 betas. Now that Apple no longer allows apps that free memory in the App Store, these apps can't get updated to compensate for whatever changes were made in 4.0. I was wondering if anyone here knew of how you can check the RAM usage and free up memory in code. I'm not a developer that gets that low level, so this time of thing is new to me. I'd like to just make an app on my own that I can use to free up memory while testing on 4.0 beta. Or possibly open-source it and host it somewhere (assuming it only uses stuff up to 3.2 that is no longer under NDA). Anyone have any pointers or code examples?
