Will installing 4.21 clear out the virtual memory hack?

    I'll be installing 4.21 when I get home later tonight, I currently am JB with the virtual memory hack. I think I do NOT want to use the virtual memory hack even when the 4.2 jailbreak comes out, but don't know how to uninstall it. I'm hoping simply installing 4.21 will get rid of it.

    Anyone know?

    The VirtualMemory "hack" is exactly that.. A hack.. And it was hacked to be used on 3.2 iOS. It's not needed for 4.2.1 and onwards now.. as it's natively turned on and being used in the OS.

    So with that said, the hack is removed, but you get a final permanent VirtualMemory solution in 4.2.1.

    I think a simple restore and update will take care of that.

    Yep I wasn't asking what it does, just wanted to know if installing 4.21 would completely clear it out.

    Of course it clears it out, whenever you do an upgrade/restore, all files are essentially removed/formatted on the iPad.

    So OS 4.2.1 actually uses virtual memory by itself--with a functioning swap file, etc...?

    I think so...

    Now we wait for all the "Isn't that a bad thing?" and the "Isn't that going to wear down the solid state memory" threads.

    I found a 64mb swapfile left on my iPad, so it's not completely wiped out after the update to 4.2.1

    edit: and the com.apple.virtualMemory.plist in my preferences folder.

    I found this also, but didn't want to be rude to the "of course" crowd lol. I manually wiped the 2 files I added in to get VM in the first place, then reloaded 4.21. I'm actually finding 4.21 to be quite smooth, smoother than the virtual memory hack which seemed to cause a lot of freezing.

    I'm finding Apple's implementation of VM to be lacking/limiting... has anyone tried the hack to see if it still works?

    Has anybody tried this yet on 4.2.1? I am getting ready to soon but would like to know if it's been tried with success first.

    I cannot operate without it though, that I've determined. :mad:

    yeah, so the virtual memory hack no longer works in 4.2.1 and this thing is now no longer my laptop replacement, as it has served for the better part of a year, but now is rather just basically a fancy (very limited) web browser.

    that pretty much makes it a paperweight to me.

    no longer recommending this product.
