When I receive a new text message and I open it, the text msg conversation opens in the middle so i have to scroll all the way down to see the new one.. it has become very frustrating
That's NOT a new text problem. Yes. solution: delete the thread of messages with that person. It only does that when the messaging thread gets to a certain (long) length. So far there's no official "fix" but if you want it to open at the proper place, delete the thread every time it gets that big, and it'll go back to opening properly until it gets big again.
I like to keep my messages, and I found that escaping out of the text and clicking back in puts it at the bottom. This is another reason I use Crunch instead of the BB text application.
