Within your browser do a Google or whatever search that will include a phone number return, tap the phone number and it will ask if you wanna dial (something like that) and the watch what happens. Java comes to life.

Ok. Seriously... necro-bumping TWO long dead threads to ask the same question in both is highly unnecessary and is a good way to get on the Mods' bad side right off the bat. To answer your question, though (since you obviously searched somewhat), you should be able to install an alternative Java platform. Most of the custom ROMs available use JBED, and I believe there is a CAB for it floating around somewhere. As far as removing Sprint Titan, you should be able to remove it just like any other program, from Start->Settings->System->Remove Programs.
I tried to install a software, it appears invalid Descriptor Error 906. What does it mean and how to get rid of this error completely?
