Although the HTC P3300 uses the OMAP 850 but I can overclock it. The X500 is faster but currently has a lot of problems right now as reported by the Users at Eten Users Forum (A site established by Users not by Eten). A lot of people are returning them back to the stores according to what I've read. I own the Eten M600 and experience has shown me that I can not get any support directly from Eten. The only support I can get is from the Users Forum. Eten website won't allow you download any firmware upgrade. Currenly, Eten has the new X500 ROM version 291 WWE; however, nobody can get their hand on it. People are still waiting for someone to hack the firmware (some X500 come with the latest ROM) in order to make it available for the others to download and fix the various problems. I am still waiting to see if the new firmware can fix most if not all of the problems; however, it will be probably a long wait
