> You can't delete the last Google account from an Android device.

The trick I used to 'liberate' people who were fed-up with the Google sync was to change the account password from a PC using the web interface when the phone was turned-off.

Then boot the phone and the account sync will error-out; at this point you should be able to delete the account from the phone.

This might have been true at one point (I know it was) but my phone didn't have my Google account on it for a few days. I could use it, except I couldn't sync my contacts or presumably use the play store. It came on but not with any accounts attached.

Was this when you initially got the phone or did you set it up and delete the account later on? Last I tried you can set up the phone and use it with no Google account, but once you add one you can't remove it without resetting to factory defaults.

It came that way from the store. As far as I know though the previous versions of android didn't function without a Google account.

I was forget that factory reset method. That's the only way to delete the last Google account.

You can. Well at least I could delete all accounts on phone.
