It also introduces support for IPv6 and now properly displays 4G data connectivity. [Verizon Wireless (PDF)]

  • LG Spectrum: This update from Verizon Wireless brings Android 2.3.6 to the mix, improves web browser launch times and switches the default search engine to Google -- for Bing lovers, there's also an option to set the default search engine to one of your own choosing.
