Cant download Opera Mini 5 to Nokia 5800 XpressMusic. Can anyone help?

[Michael S]

I tried so many times downloading Opera Mini 5 to my Nokia 5800 XM, but there is an error message which says: ''Unable to Install.'' I want opera mini 5 for my nokia 5800 so what should i do? Is there alternative websites that have opera mini 5 where i can download from? I tried downloading opera mobile 10, it works well, but i like opera mini 5 because it has the full website views rather than opera mobile only viewing websites in mobile mode (such as www.myspace.com). Please help
