At least three Linux-based phones were shown at CES this week. WNC’s GW1 dual mode GSM/WiFi SIP phone is running a version of Trolltech’s latest Qtopia Phone edition with VoIP/SIP capabilities. Motorola showed its new Linux-based ROKR E2 feature-phone too (pics, video), but the iTunes software is now removed. This feature phone uses Motorola’s new softkey-based UI. Recently, information became known for Motorola’s A1200, which uses the older touchscreen UI, same to the one we reviewed a few months ago. Unfortunately, the SDKs of these phones won’t be released to developers at large to create native applications, as Motorola is not interested in creating a compatible Linux “platform” similar to Symbian/WinMobile/Palm platforms and instead is pushing just for generic Java apps.
