Stick with iPF for secure and none damaging information. I'll give you a few reasons why.
After doing the JB on my ipad the directv app stopped working. Another forum stated that directv saved your UDID# and will permanently block the app from working even after you restore to out of the box state. That information was false. Guess what, I found no such bad info here at iPF.
Downloaded the 5.0.1 restore 732mb file from another site, well guess what, it didn't work. I downloaded the one here at iPF and it worked.
Other forums DO NOT have the quality of tutorials like iPF has. Good job Mods
Other forums are a total mess and not categorized like iPF is which makes for better forum searches.
Other forums do not have an iPad app like iPF does.
Need I say anymore...
