I think I'll take it a step further, and upgrade my OS to AOKP's latest released last week.
I am currently on 4.2.1 and it's the worst "phone" i've had in 20 years. In areas I've had service for years, it flat won't work.
Since I have to basically start over with Touchdown, and I have done it before, I think I'll try new base software to see if that cheers up the phone some.
Running a nandroid per Chief's write ups as we speak, and start over.
Not sure why the OS won't let me add the Touchdown account under account settings.
I'm starting here

flash the new OS, then flash the gapps, but I don't see anything about new radios. Are they included in gapps?
