Cingular 2125 online, but randomly unavailable for incoming calls.

Hello,
I flashed my phone with HTC Tornado WM6 Std few weeks ago. During last 14 days I'm getting information from friends that I'm randomly unavailable.

I'm using ActiveSync to Exchange email sync and Slick (ICQ) was installed on the phone (not executed anyway). Yesterday I sent a SMS and few seconds later I got a SMS from operator with the list of calls that the network was unable to connect.

I suspect that GPRS/EDGE ActiveSync synchronization is causing the phone unavailable for voice calls. But this is against the GPRS standard.

Is it "normal" for this device or it may be the Radio ROM problem (4.1.13.28_02.61.01)?

Thank you

I have a Qtek 8310 and I've been encountering the same problem all the time on different WM6.1 ROMs. My operator says it shouldn't be so (i.e. this is not their fault). In my case the problem only appears when I'm downloading something. The moment after the download is over the incoming call comes through fine.
I tried different radio versions from original 02.20.01 till 2.71.01 (from a different HTC device). None helped. I only noticed that the older 2.20.01 is more stable in general.
Well, I still don't know the answer, so let's see what other people say...

Since my last post I've done 2 things: tried WM6.1 Pro RC7 and WM6.5 and changed mobile operator.
1) with any Pro ROM radio worked very stable, without that issue, but I had to switch back to 6.1 Std ROM because it's more comfortable for me.
2) after I had changed mobile operator from a small local one to on of the federal, now everything works fine even on Std ROM.

So, the answer is probably ROM-operator incompatibility.
