when i start my phone (nokia 3250) a message appear saying that there's an untrusted software on my memory card and have to delete it from app manager.
This are the files from the application manager
a000017c.sis
a000078d.sis
a0000bec.sis
a0000c5d.sis. .... what are these files? how can i delete them. I cannot delete the files from the application manager like i delete other files. (Option - remove or pressing the C key)
