Users who have been waiting for the ASUS Transformer Prime TF201 to get an official update to Android 4.1 Jelly Bean finally got their wish today. At least, they did if they live in Sweden.

While the ASUS Transformer Pad got an update to Jelly Bean last month, users have been waiting for the more powerful Transformer Prime to be updated. While the rollout of the update in Sweden is reason to be hopeful, ASUS hasn’t said anything about Jelly Bean for Transformer Prime users in other countries.

ASUS announced the update today on its Swedish Facebook page. The post is brief, only mentioning a few caveats of the update. Those of us waiting for news on when Jelly Bean will be coming to the Transformer Prime in other parts of the world will have to wait for now.

Those of you who aren’t quite so patient may already be running Jelly Bean, however, as it’s been available for the Transformer Prime via CyanogenMod 10 for some time now. While this is the fastest way to get Jelly Bean running on your Prime, it isn’t without risks, so make sure you know what you’re doing before you attempt the upgrade.

The official update is optional, and while the vast majority of users will probably opt to install it, there are a few reasons why they might want to stick with their trusty Ice Cream Sandwich. This update removes the ability to install Flash from the Play Store. Asus has provided a link to install Flash from the Adobe website, but this may cause Flash to work incorrectly at times.

The update also removes support for Wi-Fi Direct as well, so users of this feature will want to refrain from updating.

Are you waiting for the official Asus Transformer Prime Jelly Bean update, or are you already using it via less-than-official means?
