at that price its a good buy, i bought it for 20k... the touchscreen response is slow at times and the music player is a pain... but im sure u can fix all this with by installing the new firmware
the screen/video is simply awsum....
u dont get alot of apps tho so if u can get a 2nd hand iphone 3G in that range i would go for that
not to mention the resale value of samsung vs iphone... my phone must be worth 14k in 3 jus months
