iPod touch Facetime Looking different on 2 Ipod Touch 4g

[Techuser]

I have 2 ipod touch 4th gen. Purchased at the same time with the same memory capacity. Im not sure when but at some point i noticed a difference in the Facetime icon on each of the Devices. http://news.cnet.com/i/tim/2010/10/20/FaceTimeIconF_60x60.png While the other device is listed as this http://images.apple.com/asia/education/ipodtouch-iphone/images/onthego_icon_facetime_20101001.jpg I am confused as to why this might be happening. When testing under my own roof with wifi, both devices can send and recieve calls, no problem. But why the different icons and will this possible pose a problem in the future when travaling and using public wifi's?

Have you made sure that both are running the same iOS version?

definitely different iOS version. if you're not jailbreaking, upgrade to 4.3.1

The first picture is part of iOS 4.3 and above.
The second picture is the older icon, from iOS4.1-4.2.1

In other words, Apple just changed the icon when they upgraded their software.
So you should do the same
