Updating Facebook Pages when out and about is not easy and surprisingly it’s not possible via some of the mobile apps. However, you can edit Pages by pointing your mobile browser to http://m.facebook.com. Even here however you can’t upload photos. The solution is to upload photos by email. On your Facebook Page go to Edit Page/Settngs/Mobile and you’ll see an email address that you can use to upload photos as well as status updates. To add a caption to a photo add a subject line. The only downside is that Facebook groups the pics together in Mobile Uploads so you can’t create seperate named albums. An alternative method for managing Pages when mobile is to use the full version of Facebook at http://facebook.com but even with a large screen smartphone this can be fiddly.
