Just d'ld 'ActiveFile_v1.20' and 'BTSwitch_S60_3rd' and both give that error message when I try to install them.
Any ideas?
Expired certificates!
Change Clock to several dates , until you will succeed . The message on your phone will be "expired" , or something like "not valid yet" , depending on date .
Active File v 1.20 was dated around 030209 I think . Now you can also collect v 1.43 : http://alietan.com/ . I would advise X-Plore though . After a learning curve it's easier , free (non-stop trial) and has built-in viewer , audio and videoplayer : http://www.lonelycatgames.com/?app=xplore
