The Samsung SGH-i900 Omnia is a 3.5G cellphone
Samsung sells the Omnia with Windows Mobile pre-installed, but has shown a prototype running a LiMo stack at Mobile World Congress 2009.
Furthermore, the community has already demonstrated an initial haret-based boot of a Linux-kernel including framebuffer support.
As it seems, a lot of information is known about this device, mainly due to leaked service manuals.
== Hardware specs ==
* Application Processor: 624MHz Marvell PXA312, probably a PXA310 with NAND (256MB) + DDR (128MB) in one package
* GSM/UMTS Modem: Qualcomm MSM6281, interfaced via dual-ported RAM
* Wifi: Marvell 8686 (SDIO on mmc2)
* Bluetooth: CSR 41814 (BTUART?)
* 8/16 GB external SD flash (on mmc1)
* Audio Codec / Touchscreen: Wolfson WM9713
* Screen: 240x400 pixels, 3.2"
* 5MP Sony IMX034 camera with LED flash
* Bosch Sensortec BMA020 Accelerometer
* Ambient light sensor
== Kernel Status ==
* http://git.gnufiish.org/?p=sgh-i900.git;a=summary
* Booting from haret works
* Framebuffer works
* Booting into a rootfs on microSD card (mmc0) works
* No USB device for usb ethernet yet
== Haret ==
* http://www.handhelds.org/moin/moin.cgi/HaRET
* For know we use PXA27x as arch for the omnia
* Som ongoing work for PXA3xx support: http://www.handhelds.org/hypermail/haret/current/1860.html
