Glad to hear you got messaging working. I do use mms and it is working fine. As of right now only problem is contact picker. Haven't tried contact picker 1919 yet, reading about it says it is only half ported.
I 'am very happy with my TP now. 2 weeks ago was looking at TP2. Glad I didn't get one. This the best my TP has ever been. RZ 23518 2.5 was stable but slow. Changing to 2012 has made it
FAST & so far stable.
I will be trying some tweaks and mods will let you know what I find.
These mods seem to work
