In all honesty, 3G Unrestrictor is probably in the list because that's what got first posted (and no one else talked about My3G). Personally, I have 3GU and it works fine for me. YMMV.
You'll just have to decide which one you want, as it's pretty much a case of "six of one, half dozen of the other."
I am going to move this thread to the main hacking section, primarily so that others can see it and maybe you'll get more opinion.
The second reason for the move is we like to keep this section for overviews of various tweaks that people have on their iPad. Kind of like reviews - to show off how the iPad works with a tweak.
Questions are best in the main section...
