If I delete my system cache...

[BertieHoth]

... will my Gears 3 Beta unlocks still work? I have an issue with my game saves on Grand Theft Auto 4 and I was advised to delete my system cache to see if it sorts it. I was about to, but then I got worried that if I did, I will not be able to access my Beta unlocks (Gold retro, Cole Train skin, etc) when I get my hands on my copy of Gears 3 at the weekend. Any advice? Thanks in advance!

The system's cache is for updates only. Your progress and unlocks are saved in you - well - savegame.
