the next version on FontSwap is now available on Cydia. it fixes the application for iPhone OS 3.0
many thanks to BigBoss and Dustin Howett for their contribution towards this release. the update also contains a few minor changes, that increase it’s usability for iPod Touch users.
IMP: you may notice some customs fonts will be not show up right [there's a slight shift in the vertical position], this is because the iPhone OS 3.0 fonts have different font metrics compared to iPhone 2.0 fonts and the fonts ported for 2.0 will not appear proper on 3.0, please contact the custom font authors for a fix of the custom fonts.
you can get many great fonts on the MacThemes forums, you can also request fonts you need over at that forum http://macthemes2.net/forum/viewforum.php?id=24
NOTE: to fix vertical shift of *Default* fonts on iPhone 3.0 copy fonts from
/Applications/FontSwap.app/StockFonts3/ to /System/Library/Fonts/Cache/
