I got a Galaxy Nexus on release day so I have no service on my old Pro, but from playing around with it...
It's actually very smooth
The latest .zip (2/10/2012) fixes 3G data connectivity but I cannot say that GSM connectivity even works, let alone GSM data
Here's the .zip as promised I just wiped my system, data, and cache and installed the zip, then flashed gapps and rebooted
a few things to note:
You should wipe system, data, and cache
The initial boot time is pretty long; like 5 mins or so but my CDMA data connected right away and i was able to go through the initial startup of signing into google and whatnot.
You should not turn off USB debugging
If it wants you to activate your phone and you have to press 1, alt + 1 works fine
After you log into google, you should just let your phone sit for a minute or two while your phone syncs everything again
The camera still does not work! there is no ETA whatsoever
If you do not have a separate battery it is not recommended that you flash this as we currently have no way to power up the phone if a battery dies so it is imperative that you do not let your battery fully drain on this rom!!
In order to reboot into recovery do not flash the Droid 2 Bootstrapper! Long press the power button and select reboot, then recovery
Live Wallpaper workaround: If you wish to have a live wallpaper, you may see that right after selecting it, it will turn on for a second, then revert back to a stock wallpaper. If you wish to keep a live wallpaper, right after pressing the "Set Wallpaper" button on the bottom, if you turn off the screen of your phone by pressing the power button and leave it alone for like 10 seconds, it *should* remain when you turn the screen back on. It may take a few tries.. just be sure to turn off the screen like a tenth of a second after choosing the "Set Wallpaper" button
flash the latest gapps from here -> http://goo-inside.me/gapps/
