Hello jlbaf!
well, you've done all correctly it seems - if you have put the correct eboot.pbp for psp-290 instead the "normal" one - you have to wait some time - about 20 min sometimes for satellites! download the latest version 499 from forums... and the 2nd thing - you have to be outside - gps doesn't work at rooms - so, take a walk...
Hopefully it works...
Bye!
