PlayStation Vita hacker Major_Tom just released VitaCID, a tool that gives you access to your Vita Console ID (the equivalent of PS3's IDPS).
What is VitaCID?
VitaCID is a tool that runs on a HENkaku-enabled PS Vita (currently Vita firmware 3.60 only). It retrieves your Vita's console ID and writes it in a file at the root of your Vita System (that you can later on retrieve for example via FTP).
Currently the tool is of little use for the vast majority of users, but it is expected that we’ll see “Console activation” homebrews released soon, that will let you activate a 3.60 Vita without having to update. Pretty useful for those of us who ended up with their hacked Vita deactivated, for any reason.
Get your vita CID (IDPS + PSID) and save it in ux0:CID.bin. Useful to activate your vita.
A sample activation script can be found on the VitaDevWiki. People with the relevant skills should be able to turn this into a self contained homebrew fairly soon.
You can download VitaCID from the developer's GITHub here.
To install & run, please note that you will need to have a PS Vita running firmware 3.60 with the HENkaku hack.
