Onstage dock and ipod photo

[Maybe]

I have a 3G iPod. 30 gigs model. Tech specs say: 4.1x2.4.0.73 inches it means 18.7 mm thick. The 60 gigs iPod Photo tech specs: 4.1x2.1x0.75 inches it means 19.05 mm. It means that the new ipod photo is mere 0.35 mm (0.02 inches) thicker than my old 30 gigs 3G ipod. According to you will it fit my jbl on stage speakers and my ipod armor?
Thanks
