Not working here, I restored my Vita and still not working since the 23rd. It worked the launch day but now I'm getting the "an error has occurred" message when I try to update. I understand that new hardware always gets some kind of problem during the first weeks but the lack of official information regarding this subject is annoying. Also some kind of tutorial for near will be great.
Don't waist your time calling to Sony's Technical Service they will tell you this (this is what they told me when I called a few days ago):
1) Are you sure you are connected online?
2) Reset your modem
3) We will send you an email with some information of how to fix this problem. (Of course that email was never sent).
Near worked for a while after launch but most of the time its just that damn error code when trying to use Out and About. My Near circle is full blue because I'm unable to update.
I was having the same problems with Near until I learned of a fix. If you tether your phone's internet to your Vita and run Near while it's tethered, when you disconnect your Vita and use wifi or 3G it will work properly. Thank me later.
