During installation the P800 verifies a digital signature and
certificate in the SIS file against a root certificate in the phone.
Successful verification means that you can trust who produced
the SIS file and that the content has not been modified after it
was created. If the SIS file does not contain a digital signature
you will be given a warning about the problem but you can still
decide to proceed with installation at your own risk. In general it
is recommended that you install only from SIS files where the
vendor identity and file integrity can be verified.
Note Installation of uncertified applications may cause your
system to crash and all your data will then be lost.
MIDP applications run in a protected environment with no
access to sensitive information so no signatures are required for
MIDP JAR files.
