About browser-ul mobile BOLT, I wrote before here, one and I also gave linkthe download.
A little while ago, a new version of BOLT was released (BOLT 1.5). The new version comes with some significant changes.
BOLT 1.5 BlackBerry Browser
– Server upgrades (make v1.5 15% faster thanBeta3)
– Cache support that enables directly browsing back to a previously visited page
– Download manager that downloads files directly within BOLT on JSR 75 capable devices
– Dedicated search bar, enabling search on popular search engines directly from BOLT
– Enhanced column width control that auto-aligns the text to columns for ease of reading
– Enhanced video support that includes inline media playing capability even on low-end devices.
– Support for streaming videos of any length
– Volume UP/DOWN controls in the inline media player
– Ability to rearrange the subscribed feeds using the ‘grab’ feature
– Access to History links from the URL window with inline editing OFF
– One click access on Home Page that ensures the cursor jumps to the desired widget
I tested a few videos pe YouTube, with the new one media player integrated in BOLT, and the results were satisfactory.

Download BlackBerry BOLT Browser.
Type in the phone browser: http://boltbrowser.com/boltbb.jad and start the download.

Happy browsing! :-)
Pe BlackBerry Curve 8320, the browser moves much faster than Opera Mini 5. I specify that both browsers are in Beta version.
