Opera Software has released an updated version of Opera Mini 4.5. The update fixes a bug with the bookmarks screen on some touchscreen phones. If your phone is effected by the bug, when you try to scroll through the bookmarks it moves the bookmark under you finger up and down in the list rather than scrolling the whole list. Even if your phone isn't effected you will get prompted to update every time you start the app. Here's the corrected version:
Reported working on: LG Rumor Reflex, Nokia Asha 303
Reported NOT working on: Samsung Chat 222
The app "Opera Mini 4" (141 KB) is ready to download or send to your phone as filename:"mini45u".
