Rumor has it the Nexus S 4G will be receiving an update to build number GRJ90 on July 11th, and if the above image is any indication it could be one of the first instances of Android 2.3.5 finding its way to smartphones. The build number pictured is a bit outdated at GRJ85, but according to the tipster who provided DroidLife the goods, Google Wallet using secure NFC is indeed enabled. That’s the same functionality mentioned in the Sprint update documentation. It all adds up to an intriguing possibility. More photos over at the source link below.
