LG OPTIMUS GT540 was given an official update to Android 2.1. I don’t think there will be an update for GT540 in future as LG is busy with their new hand sets. Which leaves us with unofficial ROMs.
CyanogenMod 7 is a custom ROM for Android phones with stunning UI tweaks. One Russian guy made a ROM for GT540 too. You can upgrade your phone to latest Ginger Bread 2.3.3 yeah its very tasty lol.
Ever since I updated my phone to 2.3.3 I’m so in love with my phone. Check out some screen shots below.
You can also upgrade your LG OPTIMUS GT540 to Android 2.3.3. Follow the instructions carefully.
