PSA: You can still load funds through the PlayStation Store on PSP
Got a tip in from Twitter last week that you can still add funds to your PlayStation Store wallet through the PSP! It seems a little funky and I haven't tried it myself so I'll leave it to the tipster:
"I thought it would be worth mentioning that the PSP version of the PlayStation Store can still be used to add funds and buy games despite the fact that it shut down over a year ago. It throws an error at launch then loads a blank home page, but you can still add funds and use the search function to find a game you want to buy, as well as download videos that aren't available on http://store.playstation.com (such as PULSE)"
