Why do that.
Gave it a worse of processor, and then a worse Screen, but improved the RAM.
I think it is a battery Issue, They increased the battery size to 1650 Ah.
SLCD seems more power hungry
. I guess this is because SAMOLED is more expensive to make.
TI OMAP is old, this phone looks like it's cheaper to make, and is not a step up from the I9000, I would say it's a step down.
