Getting or sending application or game from a Nokia Phone

Sending application from a Nokia 3110c is impossible( At least for me' if you disagree please comment the way)
While getting it from a another bluetooth paired phone is possible . Here is the way

• Turn ON bluetooth on both the devices
• Open a Bluetooth file exploring software from reciepents side ( I recommend Blue File Transfer v1.36 For Nokia 3110c )
• Get the jar file from the senders application location (As you will have full access over his phone using this software )
   

But Sometimes this won't work. It will say, "Invalid Application"
