The official Andriod 4.0.3 Vanilla (Ice Cream Sandwich) was rolled out for the Lenovo IdeaPad K1 in July and now K1 owners will get a taste of Android 4.1 (Jelly Bean), courtesy an XDA member called krook1. The developer claims the JRO03H CyanogenMod (CM) 10 ROM is based on the original CM9 port. The update reportedly confirms functionality for Wi-FI+GPS, HD video and audio, the external SD card, front and rear cameras, Bluetooth, Google Now (with voice) and paid apps. However, 3G services, auto brightness and the rotate lock switch are not yet working.
