There's plenty of them available used for a few tens of $/€ on ebay as it was a popular phone on Verizon network in the US. It works fine on 3G networks outside the U.S, 4G probably only works in the US. > 2) How well is it supported? Basic things like UART, MMC, eMMC, WLAN, I2C, SPI, HDMI, clocks, PMIC and regulators work with lots of other dts configured devices heading into tomorrow's Linux next in my dts branch omap-for-v4.12/dt-droid4. LCD related patches have been posted but are not yet in next. Things that currently don't work are ADC, USB, charging, audio and modems. The modems are on OHCI/EHCI, audio is on the PMIC similar to the twl4030. I'm slowly working on a driver for ADC/USB/charging with few more issues to sort out. I do have ADC/USB/charging working with my current hacks though. I've posted some notes at: http://muru.com/linux/d4/ And Sebastian has information in his blog including a device status matrix at: http://elektranox.org/droid4/ Cheers, Tony
