Opera is whispering about a “silent” upgrade to their popular Opera Mini browser that’s specific to Palm and BlackBerry devices only. Version 4.1.11355 is available at http://www.operamini.com and addresses these issues:

• BlackBerry devices can use WiFi only. [I'm assuming Opera Mini was using cellular data services and folks didn't want that? ]
• BIS might be working on BlackBerry’s. The folks at Opera say it works on one of the two service providers they tested with.
• Memory is handled better on Palm devices, which should boost image performance.

If you have a Palm device, you might want to check the source blog post on the Opera blog as it contains recommended settings for optimal use.(via Palm Infocenter)
