A rather unofficial way of updating your Windows Phone 7 device has appeared online. It seems to be relatively easy to do – you just run a file called “ChevronWP7.Updater.exe” and follow the prompts.
Although it may sound ideal for those owners tired of waiting for the infamous “Copy and Paste” update we’d have to dissuade you from doing this as it may cause problems later down the line.

“we’d have to dissuade you from doing this” – So why post it? Or are you only talking from a legal stand point?
Just from a legal and advisory stand point. Its a tricky issue. People will
want to know about this but we can’t be responsible for the issues that
could arise from doing this.
one of my mates said to connect your phone to PC and fire up zune, you can go into settings and under phone section there is an update option.
