Hope the next update will fix this, if there is a next one... P
There is a known problem with many service providers and HSDPA. If you have the phone on automatic while in 3G mode, when your phone connects to data the phone will switch to HSDPA just for the data transmission (if your provider supports it), during the transmission calls are not received and usually sent to voicemail. This doesn't happen with all providers, but it does with many of them. You can turn off just the HSDPA and not the 3G with this tweak program http://www.fit4cat.de/thread.php?threadid=263. On my phone I have no problems with normal 3G, it is just HSDPA that is the problem.

Hmm, I already tried that program but I still had the same problem even after turning off the HSDPA only. It never happens when UMTS is off completely though. I figure when I want to use the internet I will turn UMTS back on and when I just need it as a phone I can turn it off.

Press the green button to start the phone, then Menu/Options. Select the 'Band' tab and change the upper box to GSM.

Leave the lower box at 'Auto'

I replaced with a new Cingular/ATT 3G sim and still the same problem... I'm going to also try to turn off UMTS to see if this fixes it... mostly I notice when calling voicemail from the notification tab... Oh yeah, it now says ATT as my service...

I have this problem, on the Orange and T-Mobile network, with WM5, and WM6. Have the latest radio, the works.

Bit of a joke that this happens to be honest.. a phone that has 3G/UMTS but that won't allow a certain number of calls when it switches. Pretty fundemental flaw if you ask me!

I've set band to GSM, let's see if it fixes the problem. Will download the aforementioned hack this evening.

Ah, I see it's the operators problem, not the phone's. Flipping amateur of orange not rectify this before shipping..

I've used HTweakC to disable HPSABCD(sic) and will see if the problem stops.

Default Not a SIMcard problem

HI Guys!

The first trinity that arrived in the shop was mine :)
And this little bas... droped many calls.

I talked with the tecnics from my prov. first we changed the sim, but same problem. Reflashed Rom same problem.
It has something to do with teh HSDPA, evrytime my trinity connectet them, the calls was dropped, the bad thing was, we have a HSDPA antenna in teh shop

Only the change of the devise worked.

Hope was helpfull and sorry 4 my bad english!

See above, use HTweakC to disable HSDPA, but leave 3G enabled.
