Welcome to the forum. Gotta say Dark is totally right about how easy it is to fix your biggest concerns. Been using Dark's roms for almost as long as he has. (My last device was an Incite and I followed him over from LG-Incite.com.) Tweaker is an amazing app. As far as reg editors, if you like to keep everything on your device, I can share some simple tools I got from a different member of that forum, Teaomi. There is a reg editor, a reg backup utility and a reg restore utility. Here is the post:
"Here are some very basic registry tools for anyone that is interested.
It has 3 files in that zip.
The first is a registry editor that is very simple but gets the job done.
The other two work hand in hand. One is a registry backup and the other one is the restorer.
There's no need to install anything, they are just exe's that you run on your phone.
for the regbackup and regrestore, before you can use them you will need to create a folder in the device root called "IPSM"
I got these from a Windows Mobile 2003 device and they seem to work pretty well for me, but user experience may vary.

"
I have been using them for more than a year and have had good results. Anyway, have a look around and have some fun with that awesome new Dragon.
