The stable version of CyanogenMod 10.0.0 came out for the Samsung Captivate just recently. Make sure to grab the latest update to Google Apps also. Since this phone isn’t my normal everyday phone as you may have read in the past few days, I am now using the Samsung Galaxy Note II as my main phone.
I’ll continue to upgrade this old phone as I have a moment to do that, and basically plan to use it as my Spotify tunes device when I do my cardio. Screenshot of the Samsung Captivate i897 about screen are below.
