Is the IBM Java JVM file that you need to install in order to run Opera Mini on the Centro available anywhere? I couldn't find it.
I am assuming the Centro apps are pretty much all dead also, but even if so, the larger screen, threaded text, and qwerty make it a nice improvement over the DLX. The negatives are no indication of an unchecked incoming text or voicemail once the screen turns off (on the DLX the light would flash, very useful, surprised the Centro's doesn't do this) and for some reason it won't display the hotmail website, which the DLX did with Opera.
