For those of you still holding out on FRF50, here's an update to the latest leaked ROM:
You can now update from FRF72 - see Update 3 below.
For instructions please check the original FRF50 post. I'll add more content to this post as I have it available to me, and time to make it pretty.
Update 1: June 23rd, 2010, 5:41pm PST ^ID
To force your Nexus One to "phone home" to check for an OTA update, you can dial this into the phone keypad:
(that number translates to 'checkin')
For me, it pops up a notification icon saying ""checkin succeeded" but nothing else happens.
Update 2: June 23rd, 2010, 6:10pm PST ^ID
I've had people ask me on Twitter why Google would be sending FRF83 as an OTA upgrade as an incremental build. My best guess is that since FRF50 was an official OTA update for press, etc., this is an official upgrade for press members who were lucky enough to get FRF50 in the first place. The fact that we as the general public have been able to get updates since then means that those of us (myself included) who were anxious enough to install FRF72 must now wait for a build number higher than FRF83 to get our next Froyo fix.
Update 3: June 24th, 2010, 2:14am PST ^AR
