Vibrant still has intermittent 911 dialing issues on CM 9 builds. Until FaultException changes his threads to indicate otherwise or you test it, you have to assume you can't call emergency numbers. I went exactly that route - Vibrant to G2x.

Now, I'm only on the stock G2x ROM. But I'm on the audio-fixed 2.3.4 ROM (as I just got the phone yesterday, only paid $160 on eBay and it is in totally great shape). Solid as a rock and what appears to be good battery life. I used the GPS for around a 90 minutes of turn-by-turn directions and it never gave out on me.

The Vibrant was my first high-end smart phone. The G2x is my second, and it's pretty great. So it's not getting CM9 or any other ICS? Not a big deal to me; the Vibrant effectively didn't run ICS well enough for me, at least not yet. The battery life is awful on any Cyanogenmod (compared to stock) and GIngerbread on the G2x is nice nice nice. And fast.

That said, if you can swing the cash for a nicer phone, or if you have an upgrade credit coming, look at the HTC One S. If I was on post-paid and had an upgrade credit, that's where I'd be looking. I don't have $500 to blow on a phone, though, so I went a cheaper route and got a phone with great performance and a screen that won't burn in.

It's unfortunate that, due to the recent V21Y and audio updates, the G2X just became what it should have been when it was first marketed. At least it wasn't totally abandoned by LG and T-Mobile although it is now deactivated as a phone sold by T-Moble. Don't expect ICS until/if LG makes it available for the P990/O2X(non WIND model). Even then, it will take a few iterations of development to get it working well which, hopefully, will be able to happen if there are still developers working on the G2X.

Although I am extremely angry with prejudice with LG and NVIDIA, I like the G2X and I sticking with it because it now works well and I have to keep it until my 3 year non-contract-contract WINDTab+ with WIND Mobile pays for the phone which cost $500 when I got it.

Most of the newer generation of phones are not substantial or insignificant improvements, technologically, over the G2X. If you can get decent $ for your Vibrant and pay less than the $ you got for the Vibrant for a G2X, that would be a win-win for you. Even if you wind up selling the G2X later, you won't lose much if any $ as it is probably at its lowest value until LG stops selling the Optimus 2X which has updates that can be made compatible (except for the baseband) with the G2X.
