Update: The image based on V10T is almost done. Everything is working except Wifi won't connect. 🙁 Once I get it figured out I'll upload the image.
I've installed the KH5200 V10T image on my phone, and will have a rooted + enhanced version ready for y'all soon.
I don't see any differences in the phone yet, so I think it's just a bugfix release...
Still have to enter the APN, Call Display still doesn't work right unless the caller is in your address book, and SMS is still limited to 90 chars.
