In the end, I had to put my simcard into a new phone and verify.
Sorry I can't be of more help right now with the access issue.
But, some advice from my lesson: EVACUATE FROM GMAIL IF YOU HAVE ANYTHING IMPORTANT IN YOUR EMAILS.
Switch to an email account using a domain you own (and ideally use a paid email provider so you can at least contribute to them sticking around).
email or storage, I doubt that a paid service will be any better unless you are a big company.
My current setup for email storage is three fold:
* Fastmail's servers (30GB included).
* Local laptop. I have imap setup to automatically grab new emails, which are stored in a local email client.
* Automatic backups to s3. I automatically backup all "core data" folders on my laptop to s3 every afternoon.
I also backup everything on my local laptop to an external HDD every month.
I only have about $20k worth of dev work locked up in it, but it's gone.
Fuck dropbox.
iirc google requires another email as backup address for exactly this kind of situation. don't you have one set up instead of just a phone number?
I added both phone # and backup email to my gmail at some point, now I can't reset the gmail password because I only have access to the phone and incoming gmail messages and not the backup email.
Following your advice was exactly my mistake.
