"We’re seeing growing reports of users of older PS Vita firmwares being unable to access their email accounts (gmail, yahoo) through the PS Vita. The issue has beenconfirmed by some Vita hackers such as MajorTom.
People running on firmwares such as 3.01 and 3.18 are reporting the issue. Firmwares 3.51 and 3.52 seem to be unaffected at the moment.
Vita error code C2-14393-0
The symptom is that trying to add a new mail account (gmail or yahoo) on a PS Vita running a low firmware (such as 3.01 or 3.18) will yield the following error: C2-14393-0. It is unclear if the app is being blocked at the Sony level, or the mail providers.
Our technique to fix gmail on your ps vita is to fix another specific error, error C2-14396-3, and does not work in this specific situation. This doesn’t seem to be related to a POP/IMAP misconfiguration either.
Email is used massively on older PS Vita firmware to trigger various email-based Vita hacks that let user install emulators and other homebrews.
What to do if you run into error code C2-14393-0 on your PS Vita?
Users have reported success on these old PS Vita firmware with other email providers such as gmx.com, so the current recommendation is to try and create an email account with those providers. Therefore the issue people are facing with gmail or yahoo makes even less sense if it were an attempt from Sony to block hacking. So this could very well be some protocol update from the email providers themselves, that maybe the Vita email app on lower firmwares is not compatible with.
You can discuss the issue more in details on our /talk thread.
Update: MajorTom’s latest tweet seems to confirm that this is probably an update on gmail/yahoo’s end rather than a move by Sony (protocol update, as I stated above)
"Latest email application of the vita (3.60) supports up to TLSv1, old versions only support up to SSLv3. Gmail doesn't support SSLv3 anymore" - Major_Tom
