I am using 1.18 fine now. Was 1.19 just fixing issues from people going to 18 or are there other fixes/benefits to go to 19?
If you flashed the framework that was posted with 18 you have all the newest features. With 19, I figured out how to include the framework changes in the ROM itself instead of having to flash the new framework separately. One of the changes that enabled this was resigning all the system apps. This makes everything work nice together, and will allow me to enable some hidden settings (like the Hotspot settings, which I've enabled with an app for now) much easier. Look for these in the next update. If you did flash the framework on top of 18, you can wait until the next update.
The previous poster that mentioned having an issue upgrading Gmail is probably related to this resigning (still checking for sure). Basically, in order to allow someone to flash the ROM then flash the gapps while still in recovery before booting the first time after a wipe, all the apps in /system/app have to be signed with the same key. But if you're upgrading, those apps will have a different key than expected, so to upgrade the app you may have to uninstall then reinstall the app if it gives you an invalid signature error. Some setups will work, some will have the problem, depending on if you used the gapps zip or installed from the market or flashed as a non-wipe upgrade, or, or, or... I don't like problems, so since those gapps are available on the market, and the V is a US-only model where market access isn't an issue, I may just remove the gapps install altogether so this won't be a problem for anyone else. If anyone else does report the problem, I'm sure I'll edit the first post to remove those and just let those who need them to install them
