It was rumored earlier in the week that Sprint and Samsung had begun internally testing Android 2.1 on the Moment. Here we are only a few days removed and the ROM has arrived online. The update file (for rooted phones) can be found in an SDX-Developers.com forum post. Among the early reported bug was trouble logging into the Android Market. Apparently a quick reset of the phone was able to fix that. Remember kids, taking things into your own hands can sometime be dangerous and result in a $300 paperweight. Proceed with caution!
The Samsung Moment hasn’t officially joined the Nexus One and Motorola Droid as a 2.1 device but we expect it any day. If you haven’t rooted your Moment, sit back and relax. It’s coming soon.
