I like the service. It makes a back-up before every sync, so if the sync goes wrong you can go back to where you were. If your data-plan does not cost you an arm and a leg, and you do not back up your contacts anywhere, I really do recommend a service like this. It supports Motorola phones (including the V3 RAZR) and LG phones and many other phones too, even ones not listed there, if they support SyncML.
Now the contacts editor allows for uploading small pictures for every contact, so I have been adding LJ userpics for some of you I have in my list and whose picture is your face, which means that, should you ever call me, your face will flash on my screen.
I just now saw that mobical allows me to send a request email to a contact with an embedded URL so the email recipient can update hir contact info on the website directly -- if the spamtrap doesn't trhwo away email coming from
info@mobical.net
already. That would be dangerous. Who knows what pictures you guys would upload for yourselves.
