To my mind, this is somewhat a useless topic...
XDA developers are about the community and testers, about finding something new and useful and implementing into our phones or whatever. If you consider yourself "I bought a phone I need to be able to call and text messages" then you, I believe, are on a wrong site.
Besides my personal opinion about it, I have to add, that 2 years ago when I bought HTC Hero, with 1.5 version, bluetooth out of the box wasn't even working, HTC for 6 months at least was promising to release 2.1 version, at some point I just quit waiting and got here, seen way bigger progress than HTC did. When I was creating tickets asking them when approximately update will show up giving 3, 6 months as an option, they were saying - sorry we do not know exactly.
So I am surprised that somebody found that support useful
