Discovered through the usage of hacking software, Twitter user @theflow0 discovered that the Vita has a lot of internal storage not accessible without hacking. Sony did unlock 1GB of internal storage for Vita 2000 models but Vita 1000 models having 2.5 GB of internal storage is something many were not aware of.
