I cannot get my N91 to install any apps, the phone reports installation is not supported.
certificates are set to OFF, and install is set to ALL.
Any ideas people - feel free to send me samples of what U know works so I can try on my fone - SHAREWARE only please!.

Thanx

Can u plz tell me which all software are working on the N91.

TIA

Software must be 3rd Edition compatiable. There's some N91 software here:

Maybe a hardware problem, also. I don´t have one, but a friend has. But, after two weeks of normal use, the internal disk just stop to work!!! The best thing, maybe the worst thing of that device! And the assistance told him that they don´t have spares for now.
