Bored of 3G iPhone rumours yet? Didn’t think so.

The latest over on Arstechnica claims that Foxconn will be making 25m iPhones for Apple. Not only that, but the new unit is supposedly also smaller and not quite so heavy.

The newest version is the third generation of this phone, weighing only 110 to 120 grams vs. first generation cousin’s 158 grams and running on 3G mobile technology. Adopting plastic casing instead of aluminum-magnesium casing largely brings down the gear’s weight and cost by nearly one third. In addition to weight advantage, the latest version is also more energy efficient and externally smarter. LCD screen on the phone measures 2.8 inches diagonally, a downsize from first generation’s 3.5 inches.

Personally I’m not expecting any dramatic reduction in size or weight, if any. With them cramming in 3G and possible GPS I just can’t see that being possible. I also don’t fancy an all-plastic case. I like how my iPhone feels expensive !
