Reposting from the other thread I made:
Using the touch circular pad like an iPod, you can zoom in and out of webpages, and increase and decrease the size of the displayed text in messages/emails/etc.

Download Gyrator 2.

Recommended Settings under Menu>Options>Events>Rotate>Edit Event: Leave only Portrait and Reverse Landscape checked. Click Apply.
Instead of the default of rotating every direction it is turned with Gyrator 2 installed, this will allow it to only rotate between the normal portrait and the landscape that is displayed when they keyboard is open.
