Nope I only got it from a reseller who tells me that it's unused and was only given to him as a gift. He refuses to tell me anything else and this has no warranty.
My processor clocks in at 1.0ghz dual core so I don't know if this is faster than the ti omap one. My gpu is the same with the official one.
One thing I noticed about this unit is that it's a little sluggish opening and switching apps. Even typing on the keyboard has a slight delay. I don't know if I should classify this as normal because Im used to my galaxy s 2 which is lightning quick at just about everything.
Yeah, like you said, I don't know if I'm lucky or unfortunate with this.
