What's the current T-Mobile Nexus S 2.3 ROM name? The phone I saw shows that ICS is ready to be installed, but when you go to install it, and it reboots, a yellow triangle with an exclamation point shows up. It won't install.
The ROM name shows something weird for Gingerbread. We bought the Nexus S online from ebay, and the seller said they didn't know if the phone was rooted or if a custom ROM was installed.
