I mentioned ealier that I couldnt connect to tmobile/etc... well I went back to a default tmobile OS and back to this version and all is well
Very happy with everything... seems quicker, m.youtube.com works just fine too
Just wanted to say thanks to everyone on this forum and keep up the good work!
btw I had to format my card with the 4.5 OS like the others have mentioned ( I had 1 reboot, but since reformating the card there has been no problems ).
Aloha!
