A few days ago, LG made available the V21y update for owners of the G2x. Users were delighted - though the update wasn't major, it did seem to bring some notable additions, according to this unofficial changelog:
- Update to Android 2.3.4
- Built-in Google Plus capabilities
- Swype 3.26.92
- New RIL and baseband (dated March 11, 2012)
- Improved battery life
However, the update was pulled shortly after, though those who'd managed to grab it found it quite stable.
