Messaging app? Are you by chance talking about how you have to open the app every time you want to see if someone msged you? I get so irritated by that. It would be nice if a notification came up on the front screen.
Also, if your talking about how there is no flash player in the web browser, I highly doubt it will be coming soon.
Personally I think they should allow themes for the vita not just wallpapers and yes the msg app is horrible and i hate how you have to sign in every time your vita goes to sleep. I wish it just kept you signed into your account until you power the vita down. Also let me download games that are compatible with both PS3/Vita. Like minis or downloaded psn games that work on both..
Also, there should be a feature for recent friends or allow us to add friends by clicking a player's profile. That would be nice. They also need to consolidate the party, group messaging, and friends app under one app. This would free up a lot of room on the home screen. Make it so that people on the PS3 can see people on the Vita and vice versa.
You can get messages auotomatically, but in 15 minutes under settings, it should though be automatic like when friends come online. About the web browser not flash, update the HTML5 video, they said that they are improving the browser, so it should come soon.
Yes I totally agree, whenever I play BF3 on my ps3 and get a invite for example, and then later on when I go onto my vita, I get all excited I get a new message, but really it was same one.
