The ASUS Transformer Pad TF300 Has been receiving a very quick Jelly Bean update in the UK as part of their OTA rollout. However, the US hasn’t bee so lucky. Well today, ASUS put up the official update file on their website. The 440MB file only works on US TF300′s, so if you don’t want to wait for the OTA, you can go get the update now. However, the OTA should come eventually and update your TF300 in a much easier fashion. So it’s up to you what to do, because both paths are 100% official. If you’re tired of waiting, hit the source link to the ASUS website to grab the update file now.
