Hello guys, With a Nexus One, is it worth upgrading to 2.2? I have found some ROMs for 2.2 but they say its still buggy (like VPN won't connect/app2sd wont work). My questions: 1- Is there any new rom that has those problems fixed? 2- If I upgrade to 2.2, I can still root my phone and unlock the bootloader and install all apps from the market, right? 3- Are there any themes for it?
