Following the international model upgrade from last month, the SIMFree Galaxy S3 Jelly Bean update is rolling out now — at least in Europe.
Arriving as over-the-air (OTA) update, the new S3 Jelly Bean update weighs 285MB in size; so make sure you’re connected with a stable WiFi connection. If you’ve not gotten an OTA push, you can always check for the update using Samsung KIES and USB or manually by heading to “About Device” in settings and choose update.
On the other hand — despite citing the Samsung’s unspecified confirmation from earlier this month — it looks like the Samsung will roll out Android 4.1 Jelly Bean Update for US Galaxy S3 models [carrier-bounded] starting tomorrow, October 25th. Stay tuned for a follow-up post.
