I noticed the other day that my Tilt is not allowing me to simultaneously access the data network while on a phone call. I've always been able to do both while on HSDPA. I've tested several times on my phone and my boss's Tilt and neither of us are working.

I'm running the new HTC 6.1 ROM, but my boss is running one of the AT&T Tilt roms and it was working for him before and he hasn't made any changes that he can remember.

Does anybody know if AT&T has made a change? Do other people have the same problem?

Have either of you run the Kaiser Tweak and changed the "disconnect after..." setting under the data section? That will kill the ability to access voice and data simultaneously. Set it to default (disabled).

DOH! That was it. I should have known better. Thanks Creepy. I appreciate your help.
