I have a N81 phone. I have tried installing games of all sorts to my phone. Firstly, I tried installing games in RAR format, and then found that there is no way i can find the system folder in my phone, in order to paste the APPS & LIBS folders in, even if I try 'display hidden files'. Secondly, I tried installing some in .sis format, but I get this installation not supported error message. Games I have tried installing are Pathway to Glory, and Ghost Recon Jungle Storm. I have already tried reformatting memory card, and reinstalling latest firmware on phone. Please help me out, it seems like i cannot install anything.

The N81 will mot run any pirated (or otherwise) N-Gage games intended for the original N-Gage or N-Gage QD devices.

Go to http://www.n-gage.com/ to get the new N-Gage application and the games available for it.

i have the same problem

And you think the answer for you would be somehow different than for the original poster?
