Been away form my 770 for 6 mths. Found it my 770. Was fooling around with changing the OS back then and had no luck. What is recommended now for the 770 to update to? Advice would be appreciated, thanks.
PS-link to it would also be appreciated. Thxs.

OS2007HE is your best bet at the moment.
Cheers, -John

Maybe . . . but personally I really like OS2008HE.

Really, the only way to decide is to try them all for yourself.

Thanks for the info. Where can I download the OS and does it have directions on how to install? Appreciated, thanks.

downloaded the bin file-instructions didn't show how to install. Can someone give me directions on how to install this OS? Or show me where to find the instructions? Thxs!

Download the bin file, go to the nokia 770 website as the docs say, find a lack of downloads, then go to the 810 page, download the flashing program, run it (assuming a windows machine here), connect a USB lead, restart the 770 holding the home key, and follow the instructions. Shortly after, you have update.

Did it this afternoon. The webbrowser seems flakey as anything, and I no longer can see my wireless (saw it once to add it to the list, now it can't find anything). Other than that it works ok!

MAn no luck following your instructions-could not find the flash program. Could you direct me to these instructions yoy are talking about? Thanks.
