Where do I find a working Pure Edge viewer for mac OS X? Finally there is a Solution that works. (Scroll down for a working solution download.)
Normally you would install PureEdge forms viewer on a Microsoft Windows machine but if you own a Mac, it is a not officially supported directly on OS X.
I downloaded an Intel Mac version of PureEdge viewer from grants.gov but when I tried to install it but I got this error:

I put together a work around to get the installation to work but there were functional problems with form navagation and printing. Thomas Kearney from AEONCONCEPTS.COM put together a good emulator package that allows you to run a more updated version of PURE Edge 6.5 Viewer on your Intel
based mac. It uses the opensource WineSkin project.

PS3 Downgrade from 3.56 to 3.55 Jailbreak,
Update:
Sony has released 3.60 firmware patch. This update apparently disables firmware updates from a external device and has reportedly banned "Jailbroken" from the Playstation Network.
There is a way to downgrade your PS3 Slim firmware from version 3.56 to 3.55 or lower.
However, there are a few fake sites out there (like www.ps3tuts.com) that are just a scam.
In the www.ps3tuts.com scam, a link to surveys and a paid "premium link" that contains a link to a file containing a comment poking fun at you for falling for the scam.
Simply only use verified sites and don't pay for it.
For older PS3 slims only, you can simply go to system settings -> restore PS3 System to downgrade your PS3.
The 2 people that did do this successfully had a copy of 3.41 OWF (PS3UPDAT.PUP) on a USB stick saved in /PS3/UPDATE.
Whether or not this had any effect, I am unsure.
My source for the previous tutorial was mistaken on needing to brick your PS3.
This will not work for fat PS3's only the slims that originally shipped with OFW 3.41.
Some basic things to do before attempting jailbreak methods:
Install a new hard drive:
To install a new hard drive, you will need to first re-install 3.56 using Sony's original firmware (save the update file you used for later), install the harddrive, and run a format/ restore using the update file you saved
If you don't you will get a Data Corrupt 8002F225 error, even with the correct 3.56 firmware downloaded from Sony will give you this 8002F225 error no matter how many times you try. My guess this is the bug that Sony fixed with "3.56v2". At least if you have your original PS3 hard drive, and your PS3 will still be functional if you plug it back in.
Create a backup:
Creating a backup will prevent all your saves from being deleted, your music, photos, and other items etc. to be safe.
To create a backup, insert a USB device into the USB port onto your PS3. Navigate to System Settings-->Backup Utility-->Back Up-->Yes
To restore your backed up files back on your PS3, navigate to System Settings-->Backup Utility-->Restore
