I just received my first T-Mobile html e-mail, I've had 4.5 for about 6 days now. I think this might be a sign of the official release soon. Has anyone else had this happen yet?
Well it depends on the server enabling it. None of my previous emails have been html with 4.5, so hearing 4.5 was supposed to be released sooner than September, it might be within a few days, as they have enabled it.
BIS upgrade was over a month ago. I don't think that suddenly being able to receive HTML emails (which requires 4.5, and which you have) is a sign, as nice as it would be.
