Proud new owner of a rooted G2X, but rusty with the recovery.

First off, thanks for stopping by to assist. Secondly, I just bought a used G2X off ebay and it came already rooted, with super user already installed. However, there's no rom on there and it's still running Froyo 2.2.2.

I haven't messed with rooting, recovery, or ROMs since my G1 so I'm quite rusty, leaving me with a few questions.

1. I know LG just released a Gingerbread update, yet I can't access it or any of the previous updates through the about phone update area. That's because I'm rooted right? I wouldn't mind just having stock 2.3.4 on here for now.

2. I don't know if the previous owner already put a custom recovery on here or not (not very talkative) so is there a way for me to check that? I was reading that if I boot into recovery without a custom one installed, the default recovery automatically starts wiping and reformating and I don't want that.

3. And just a general consensus question, coming from my horrible Samsung vibrant, GB roms are the way to go with this phone right, avoid the ICS?

Thank you in advance for all your help. Appreciations.

That's what I was going to do, but then I read this:

To perform a master reset using the hardware keys, follow these steps:

Back up all necessary data. See: Prepare for a master reset and back up data on Android
Turn off the phone.
Press and hold the Power and Volume Down, key.
The phone will turn on and display the LG Logo
Wait 30 seconds and thephone will display the open box and arrow pointing towards the phone.
Release the keys, and the phone will reset back to the start up screen.

And so I'm catious about checking that right now because I don't want it to reset right now, kind of has used to use it right now.

I actually miss root, so I think I will stay rooted and check out one of these nice GB ROMS. Man, I have missed custom ROMS lol Now it's just a matter of deciding which is the best to use. So out of th eloop anymore on this stuff.

And yeah, the G1 was an adventure. Soft bricked it twice before.

I forgot about my own thread! lol But thanks for all the insight and help. Currently running into a mobile network/data drop issue so taking advantage and flashing a whole bunch of different roms. From MIUI to Kang Banger is like 2 opposite ends of the spectrum, but I love them both!
