hello

i've been reading a lot about self-signed certificates and a lot of people seem to know a lot about them and i was wondering if anyone can help me. i have a nokia n73 which runs s60 3rd edition, and when i created my theme .sis file and transfer to my phone, it says certificate may not be valid, expired,or phone clock settings incorrect.

the 2 solutions i've already read about on this forum is to use the cygwin program to create the key and cer file and the other to syncronise phone time and computer time

i've downloaded cygwin and created the .key and .cer file from that and it still doesn't work. i've also made my phone's time settings the same, earlier, and later than my computer's clock time.

i would really like to create my own themes!

i would really appreciate the help!
