Update: Still no connectivity between the PS3 and Vita with LBP2
Will update with more info as we test it out."
From wololo (via wololo.net/2012/12/19/psvita-ofw-2-02-out/): The PSVita OFW 2.02 has been released. As usual it is just 'minor bug fixes'. At the moment, it is not forced.
This update seems to be safe. I have gotten in touch with The Z and he has confirmed that everything still works fine on 2.02, it seems like this one really is just some minor bug fixes.
The Z took the time to make some videos of eCFW running on 2.02:
So, it is ok to update! Now just sit tight and wait for Ninja Claus!

Do you have a PS3 with the same PSN account and if yes have you changed your notifications settings there after you've set it on your Vita? If yes - that's most likely what's causing this as those are linked together and changing settings on one system will affect the other and vice versa.
The funniest part is that while PS3 is still missing the advanced notification options Vita has (in the menus so you can't actually configure it directly on PS3 itself) is still actually adhere to those set on Vita.
patiently waiting for ninja claus to release the new exploited game to regain psn access. Until it's released there is no need to update. i'm very happy with the mad blocker exploit and playing assassins creed.
