Everytime i changed my file from .rar to .jar file n put it to my phone,i cnt install it.Everytime it installed till halfway,it 'll sae operation failed.Anione no e reason???

Try to extract the game which is included in the .rar file using winRAR. Most of the times the .jar files are contained inside the .rar files and we have to extract it..!

Y it is .rar de???how do i change it for use???

you right click on the .rar file and click extract here, then if you find a .jar file you put in it your phone and install it.

operation fail? could it be that your phone does not have enough space? im sure that even if the file type is unknown to the phone, SE phones will still receive the file and put it in the Others folder
