    Sign4ever did work for on the app. It still doensn’t install because the cerificate expired problem. Could this problem only be solved when i put the original productcode back on my n97?

    Thanks in advance.

    @ Amir, with xplore you can read .doc files i don’t know about excel and powerpoint but maybe you can find an app just for that. To watch .avi movies download SmartMovie and crack for it so you don’t need serial code… mp4 and 3gp videos can be watched from the phones software. xplore and smartmovie are ‘lonelycatgames’ apps…
