BOLT is a free downloadable browser that offers an uncompromised browsing experience on even lower-end mobile phones.
Rather than offering a simplified, mini version of the Internet, BOLT provides users with a fast, efficient, feature-rich way to enjoy full PC-style web pages and rich media applications on all levels of mobile devices.
Built on Bitstream's ThunderHawk browsing technology, BOLT is the result of 5+ years experience developing mobile browsers that optimize usability, speed and performance on resource-constrained systems with limited memory, processing power and screen space.
I have been using the browser for several days now and it is LIGHT YEARS ahead of the Blackberry default browser.
Something nice to point out is, "BOLT can be installed on nearly all Java-based handsets since the browser requires only Java MIDP 2 and CLDC 1.0 or higher support."
I am seeing a little bit of lag on my Curve when moving the mouse cursor around, but the pages themselves load amazingly fast.
Give it a shot... the beta just went public.
