Well, well, well - looks like there was more to yesterday's Nexus S GRJ90 leak than originally met the eye. Though the update doesn't contain many changes, the bigwigs at Mountain View apparently deemed it substantial enough to warrant a new version number: 2.3.5.
Again, the update includes:
- Fixes for the Nexus S 4G's signal reception issues
- A 4G settings widget for the Nexus S 4G
- TTY (teletypewriter) support
- NI push support
- The NFC secure element, which is critical to Google Wallet
So there you have it - assuming that Droid Life's sources are credible (and given the blog's track record, I'd say they are), you'll be able to refer to the update that should be hitting your Nexus S 4G next Monday not only as GRJ90, but also as Android 2.3.5.
