BitStream just gave me 500 referral codes for the Bolt Browser that I reviewed last Friday. If you don't have Bolt, go to http://boltbrowser.com click the "Download" tab and fill out the form, entering wapreview in the referral code field.
I also found out a little more about Bolt.
Versions and Upgrades: The initial release of Bolt was version 0.70, the latest is 0.73 - which is what you should have if you downloaded after 9 AM EST on Friday. There is another release in the works although I have no ETA. If you don't have 0.73, go back to the Download page and request a new download. I don't think you need a referral code for updates, the site should recognize you as a returning Beta tester based on your email address.
Bolt is based on Bitstream's ThunderHawk Browser. The underlying ThunderHawk technology supports BREW, Windows Mobile and Symbian and it is planned for BOLT to support these platforms in the future.
Phone Requirements:
- J2ME MIDP2 (virtually all J2ME phones produced in the last three years)
- BOLT supports all common/standard screen sizes
- Approximately 150k storage space for application
- 500k of RAM to run application
Bolt Architecture: Bolt uses the WebKit rendering engine and Bitstream's proprietary fonts and font engine on the server. Content is compressed 23:1 before being sent to the handset, reducing data traffic and page load times.
Multimedia and Plugin Support: BOLT supports Flash video. The client/server architecture is used to transcode the video on the fly into 3gp format, then send to the device. In some devices (e.g., Motorola RAZR), video is played directly in the browser window as it would be on a PC. In others (e.g., BlackBerry smartphones), the video is played through the device’s native media player via the native browser. The device’s capabilities determine the process used to display video. Video that is in mobile 3gp format is sent directly to the device without transcoding. Bolt supports Ajax (except for timer events).

If you missed out on the first round of Bolt invites last week, now you have another chance. If your phone supports Java ME, I highly recomend you give Bolt a try.



First make sure you are using the same access point settings for Bolt as work for Opera Mini.
Try the multi-signed version first, if it fails try the other signed versions. If they fail then try the unsigned ones.
If none of the four versions of Bolt work file a bug report at http://boltbrowser.com/support.html giving as much information as possible including make and model of phone, name and country of your mobile opperator and the exact error message
It's supposed to work on "dumbphones" The Bolt site even has an image of Bolt running on a Motorola RAZR2 on the homepage and the FAQ says "BOLT can be installed on nearly all Java-based handsets". I suggest you file a bug report at http://boltbrowser.com/support.html
