yes you can update your Lumia 710 to WP7.8. However, it is still not yet available for download via Zune but it will be released early 2013. About your data, before you'll get to the process of the update, you will be asked first to backup your information. So no need to worry about your data It will be safe.
Hope this will help you.
I think you should lost, downloaded apps, data, manual settings. After update should have your phone interface like completely new.
Yeah, Thanks for clarifying that. I forgot to mention that one.. It would be better if we will manually sync first the media files via zune before performing the update. However, in my case, when I updated my Lumia 800, for some reasons all of the apps and data are still there nothing was deleted. But again, just to make sure, sync the media files first before updating the device. with regards to the apps, you can redownload it again via Marketplace. Also, text messages will be deleted.
Wait for the notification on the phone telling you the update is available and then connect to Zune to download and install it.

I'll updated my Lumia 800 to WP 7.8 too,
but my phone indicates that there are no updates on the site of nokia is that for my phone is an update,
what can I do
Looks like Nokia don't care about keeping existing customers happy on the assumption we'll all rush out any buy whatever the latest and greatest is.
I just spent an entertaining half hour on line with support typing to work out exactly when my 800 would get updated. I kept being told "three weeks from when the rollout starts" but... apparently the rollout start date is different and is dependant on your operator, your region and your device batch number. Now I got my device unloaded in Norway and now use it in the US on T-Mobile, so their suggestion of contacting my operator is no use, and I don't speak Norwegian well enough to try and ask Telia to help someone who isn't their customer. You'd think Nokia and/or Microsoft would have some sort of clue about this (it's not like it's the first time they've rolled out an OTA for WP7.x)
So ... my current contract is up at the end of the month, so the race is on... if the 7.8 update appears in the next few days then I'll stick with WP7.x a bit longer, and maybe when I finally get frustrated enough to upgrade there will be a decent selection of "real" apps in WP8 (not just 3rd party clones) and I'll remember fondly how Nokia managed to keep my phone alive for a little longer with a timely update to 7.8 ... if the update isn't there then it's an easy choice with unlocked Nexus4's being available again
The exact dates are not announced by Nokia. As the updates are made available in staggered manner, you need to wait till its released for your device.. No other go but keep on checking ...
It is 21st feb and I'm still waiting for 7.8 update on my Lumia 710 here in India. Update check option is enabled and the Zune tells me my software is up to date. Any idea when will i get the update??
