We were recently contacted by scene member d4kc9 who was able to use an unactivated sim card to browse the web on his Vita. Now, before you think a gigantic loophole was found: this AT&T unactivated sim card lets you browse… att.com only.

Alright, so, nothing groundbreaking here, but as d4kc9 states himself: ” I know this might not be much, but I hope it inspires people to mess around with glitches like this.”

What’s interesting here is indeed the way people find crashes/bugs, and how they can turn into vulnerabilities ultimately: in this case, d4kc9 messes up with the sim card activation process, by exiting the process at an unexpected time. By then, the device is connected to the att network for the activation, meaning the browser can also navigate that site.

It is very likely that the sim itself is made in a way that only the att urls can be accessed, but one can dream of a more major glitch, where messing up with some DNS settings could let you access more, or turn att.com into some sort of proxy for more browsing (I kid. If you attempt to hack one of the major network providers just so you can play online on your Vita, you’re playing a dangerous game!)

Details from d4kc9:

The Sim card that is included with the PSVita in the US is locked to the AT&T network. This sim can surf att.com by going to the activation wizard for AT&T, touching connect then exiting during the connection process quickly by hitting the PS Button. The Vita will continue to connect to HSPA+ (3G) allowing you to go to the regular browser and connect to att.com. I know this might not be much, but I hope it inspires people to mess around with glitches like this.

And yes, Still not sign of a hack for the memory cards, so you’re going to have to check what the best size is for your next vita memory stick.
