Just a quick post to answer a a pertinent question: Do you need to apply for a new code in Phase 4?
(Made edits to clarify a few things)
Answer depends on a few things:
Are you already a beta tester and have been participating in any of the beta phases?
If the answer is Yes – No, you do not need a new code. No you do not need to re-register.
If the answer is No – continue reading
Are you a beta tester with a beta code but never registered and never participated in any of the beta phases?
Register your code now and activate it, if you do this, you will not need to apply for a new code for Phase 4.
If you did not register it before July 30th, you will need to apply for a new code for Phase 4. Read this.
Are you are reading this after July 30th, and had a beta code but never registered it?
You will need to register again once Phase 4 starts
Are you trying to get a beta code via registration?
You need to go apply now, the deadline for this batch of application is July 22nd. Apply here.
Are you reading this after July 22nd and was not in time to apply?
Try to apply during Phase 4.
Are you not receiving any beta codes despite multiple applications?
Nothing much can be done here, if by Phase 4 you have still not received a beta code, you will need to apply again.
