hi, im planning get an iphone 3g, but my fren told me that 8gb and 16gb got little bit different, he say some software only can install in 16gb, but not for 8gb..... it sound weird, i not very trust, that why ask here....

And is that iphone come with organizer software like wm - outlook, palm - palm organizer, for sync contact, notes and blablabla , backup purpose....
