Sony Ericsson upgraded the X10 to Android 2.1 in November, and had planned to stop there, but customer demand and technology advances prompted the company to consider another upgrade.
"We have listened to our consumers," Sony wrote in a blog post. "In addition, the development of the software for our new 2011 range of Xperia phones gave us a solution that made it possible to deliver Gingerbread on Xperia X10."
Sony Ericsson decided to bypass the Android 2.2 update because it has been focused on Gingerbread for its upcoming line of Xperia phones, including the Xperia Play "PlayStation phone."
The rollout, which will technically be Android 2.3.3, is planned for the end of the second quarter into the third via the company's PC-based upgrade client. At this point, the Xperia X10 is available from carriers and in a version not tied to a specific wireless company, and the Gingerbread update will initially be provided to X10s not tied to a carrier.
