Google Nexus S users on T-Mobile might be having a bit of trouble using the video chat feature, which has recently been added through the latest Android 2.3.4 update. Specifically, this issue comes when users try to use this Gtalk video chat over a 3G connection.
It was assumed that T-Mobile decided to only allow such calls over a Wi-Fi connection and therefore blocked 3G video calls. However, it seems that the issue turned out to be the result of an engineering constraint of the device and perhaps Google has fixed these issues.
