Apps I have installed:
Titanium Backup -freezing/deleting apps, I suggest freezing
Setcpu - underclock your cpu, battery saver, it's dynamic, so the cpu mhz will ramp up when you need it
Clockwork mod, not sure when I got this, probably when I first rooted, that was on Gingerbread.
Other resources.
XDA forums, tmobile.com forums.
Like I said it's a pain, but it's worth it.
Not even a thank you from ma3loom, not ever am I going to take time to write up help instructions for someone on this forum again.
i also had bluetooth connectivity issues but no other noticeable issues
I just did the Android 4.04 T989UVLH1 update over Kies and my phone works MUCH better now, everything is smoother and faster, no lockups or reboots and the battery is lasting longer.
Now my phone works like it did before the ICS update. Very Happy!![]()
