sorry to keep bringing this up guys, but I really need some help/guidance/ideas/pointers. I have tried checking the SMS-related registry entries I could find and comparing them against a working 20270 build from the kitchen and couldn't pinpoint differing entries. I think that something in the SYS folder maybe missing or "misplaced", and this could be the reason that causes me to not be able to send text messages, but I'm not very knowledgeable when it comes to the low-level stuff that we use to make our ROMs.
That's why appeal here in the hope that someone can point me in the right direction.
Thanks everybody!
