Can I use Java for recovering lost text messages from my cell phone?

Hello , my problem is this...
I accidentaly deleted some very important messages from my an old cell phone.
My unluck is that the cell phone do not have an "trash" folder for deleted messages, and

my luck is that it's supporting Java.


Do i have any luck to write an applet and ask the cell phone to run it, in order for me to clone the whole cell (meaning to RAW read/write data) from phone to an SD card, and and to recover the lost cell phones?
Or these cell phones are running java into a separated enviroment, because i can't run java from an sd card, only from the browser (i don't know why)


I am an PHP programmer, and also used to code in C/C++ in the past..

The answer to this is almost certainly no, or at least not as you have described it. There are programs that can recover deleted items, but I have no idea how well they work with cell phones. I suggest you stop using the phone and do a google of something like "file recovery software" to get an idea of some of your options.

Were the missing files, OS files or files within an application? An application can have its own "files" within a single OS file.
What OS controls the file structure?

I would like to recover some deleted text messages, i have no idea where there is the slot file with the SMS messages.

thanks
