Just after a week of its launch, the Google Nexus S is getting its first software update over the air. The OTA (Over-The-Air) update weighs in at 1.9MB and carries the build number GRH78, up from the previous GRH55 build number. There is no official change-log but looking at the size of the OTA, don’t expect wonders. Apparently, the update mainly fixes some bugs and Maps fixes’.

MoDaCo owner Paul posted on XDA with regard to the OTA update :

Super quick GRH78 analysis – changes to framework.jar, kernel and Maps.apk. That’s about it.

Nexus S owners can either wait for the update to be pushed to their phone or enter *#*#checkin#*#* manually and get the update.
