There must be a reason for this.

Maybe they run some spyware in the background you could suspect to exist once you compared the memory you use yourself with the memory still available?

It's easy to spy on others using their iPhones and there are several ways the iPhone calls home or can be remotely run by Apple (for instance to delete prohibited apps) so that would be no wonder.

There is no shortage of apps in the App Store that show free memory.

onreact-com2• 17 years ago

No. Did you read the article? They removed ALL of them not just this one.

Author fails to mention that they are using an undocumented API to retrieve this information. Staying away from undocumented API's has been the rule since day one.

What the fuck are you talking about? Making a goddamn syscall to get the VM usage of other processes is not an undocumented API.

Yes -- the API (host_statistics() on Darwin) is in the public headers and is not private.

Of course, it wasn't the ability to show free memory that they removed, rather, the ability to trigger OS low memory handling by allocating (nearly) all available free memory.

I'll repeat what I commented on Mashable... the "most useful feature" (which is "freeing memory" not "showing free memory, that still works) generate a lot of crash reports.

Whenever you hit the "free memory button" iStat fill the memory of the device until it receive a "low memory warning". In the mean time all background apps are zapped which includes Mail, iPod, ...

I can see why Apple is annoyed to receive crash reports because an app willingly force theirs to crash (gracefully).

Still, iStat is a great app, beautifull and functionnal. I personnaly won't miss this feature.

The concept of "free memory" on a modern system also makes no sense. RAM that is not used is wasted. (Up to a point; the OS will try to keep a percentage actually free so it can always do some work, but this is not much compared to the total.) The more of your RAM that is taken up, the more data you have cached.

The problem is that the iPhone OS tends to have issues with releasing memory especially in high-pressure situations e.g. games. It's quite frequent that out of the ~60MB non-OS RAM of a 3G a game only gets to use 10~20MB, and lags (or even crashes for the most intense ones) because of that. The initial "solution" was to reboot the damn phone in order to kill the MobileMail and MobileSafari background processes.

"Free memory" functions give users the ability to kill those without having to restart the phone, which far shorten the time it takes to "reclaim" all your ram and be in an ideal position to launch a demanding game.

And apple's ripping on WiMo's task manager comes to bite the users's asses.

Yeah but if Mail (and Safari, of all apps) didn't stay running in the background the low mem issue wouldn't happen in the first place…

No this is COMPLETE BS. I haven't cared about Google Voice and all of the other apps that were rejected. But I have personally used iStat and it's predecessor app for a long time. It was the only bloody way for me to know if my edge & 3g phones were going to crash from lack of memory. I have never had problems with these apps. As long as you followed the clearly written instructions about how to free up more memory, you were fine. This is some official bullshit.
