Today I found a nice little free java based application for Sony Ericsson Mobile phones which will help you to read Adobe PDF Files on your SE (Sony Ericsson) handset.Generally there is no official (Jar) Java PDF reader for Sony Ericsson models but somehow I got this PDF reader jar file and when installed on a friend’s cell phone, it worked like a charm! It is amazing how people can create a PDF viewer for non-smart phone devices like Sony Ericsson when the official SE team haven’t developed any free adobe mobile application for this 
Anyway to view PDF files you have to download PDF Reader (Download links given below) or send it to your Sony Ericson and install the application.As far as I know this PDF reader supports the following Models
Sony Ericsson k750i
Sony Ericsson W810i
Sony Ericsson k800
Sony Ericsson p990
Sometimes you might get a “Invalid Application” or “Operation Failed” error, in that case try to re install PDF reader application! As Sony Ericsson mobile phones support .Jar file extension,I have uploaded the PDF Jar file to different file hosting! If you are not able to resolve and read PDF documents then put up the issue here via comments..
Download Sony Ericsson PDF Reader
Sony Ericsson PDF Reader [Rapidshare] || Sony Ericsson PDF Reader [Mediafire]
Update: OMG! Never noticed that this PDF reader is flawed.. please do not download. I will try to find a free pdf reader and will update this post. I am sorry.. damn, I suck 
Will definitely update this post asap. (20th march 2010)

Hi firend,
