Update: The link to the update is now working. Get on it!
Infuse 4G owners have been chomping at the bit for some Gingerbread love since the device's release in the middle of last year, and it seemed this morning they were finally going to get it. A moderator at the AT&T forums posted up the typical changelog marketing spiel, chocked full of customer benefits and exciting new fonts like 'Choco Cooky' and 'Cool Jazz' (I am not kidding).
Unfortunately, it seems AT&T neglected to inform Samsung that it was update go-time - the link to said update 404s. Whoops. Of course, if you have Samsung Kies installed, you should be able to check for updates using that.
