a g900 will have the same speeds as your current k810i, they work off the same bands.
The c902 has 3G, but only in Europe.
May I suggest that if you're in the United States, get the k850i, which has 3 and 3.5G plus a real flash and led light, unlike the g900 and c902 which only have led.
wifi is fast though...
Im looking to replace my k810i that i got in hong kong (so i know they will both work in my area) but im not so sure which one to buy. Ive looked at review photos from what im guessing are prototypes? and the g900 photos look washed out, also im wondering if anyone know if the flash is decent on it?
i cant decide which to buy.
c902: 3g, edge and quadband
g900: Touchscreen, wifi but triband w/o edge or 3g
What are your guys thoughts?
