Originally, the Dell Streak was supposed to receive an update to Froyo (2.2) before the end of the year. Well assuming that this e-mail, dated December 7th, obtained by StreakSmart is correct, the update won’t come until at least January 12th.
As you can see, if you have an “unlocked” device, then you should be able to grab the update now by going to Settings > About device > System updates. The only devices having trouble are the ones locked to AT&T. While one more month until the update rolls out doesn’t seem like too long, spending that month on Donut must be torture. We’ll be sure to update you on the situation should anything else pop up, but until then, maybe some sort of relaxation classes?
