I am posting this info in regards to the wiki site and a few others that really are difficult or impossible to view on the sidekick. I have tested all four of the mobile proxies I use and they seem to make the wiki much more viewable and less load intensive on the sidekick. I still can't sign in, but at least I can view it.

These proxies work for a lot of sites that aren't normally viewable on the sidekick browser:

Googlizer:http://www.google.com/gwt/n
Skweezer: http://www.skweezer.net
T9Space: http://t9space.com/anysite.html
HOWP: http://howp.hiptools.net/ *currently HOWP is shutdown*

So for example - I used skweezer to view http://sidekick.wetpaint.com then I saved the skweezed address to my bookmarks so I could always pull up the Sidekick Wiki and view it on my SK.
