FWIW I tested this (Vodafone UK) this morning by starting a call on speakerphone from n900 to my landline, leaving it open, and then kicking off a remote control session (rDesktop) on n900 over a 2G connection (5 bars).

The voice call continued with good quality & without any glitches, but the RDP session was slower to establish than normal, and sluggish once connected - fair enough, you can't get a quart from a pint pot as they say.

Ending the call didn't appear to significantly speed up the RDP, but that may be me being too subjective as I'd expected an noticeable improvement.

I then repeated by starting the RDP session and calling the mobile form the landline - did this twice, both times Igot the call presented on top of the (full screen) RDP session, first time I acceted thecal, waited a bit then disconnected . Second time, I rejected the call. Both times the RDP session remained live after hangup

So, Voda UK is definitely able to cope with simultaneous voice/data on 2G, and the n900 is not to blame if your cellco doesn't allow this.

edit - just saw above post linking to old thread about phantom calls - this is a separate issue, where the phone loses it's cell connection entirely & needs a reboot to fix it. AFAIK it is unrelated to the issue in this thread (where the phone will automatically begin to take calls again once the GPRS goes idle).

esit #2 - just a thought, rDesktop is a pretty lightweight protocol, so the above test may not be fully conclusive. So, I swapped the RDP for a download of a 2MB .pdf from a website, and repeated the tests. Again, incoming calls were always presented, and I watched the .pdf download progressing (via file manager) while I was still on the call to myself (I could see the doc filesize increasing in real time). So, Voda UK deffo "multi-tasks" voice & data admirably well under a variety of circumstances.

yes the problem can reside with operators.. but the issue is that its not happening in case of N900 only.. my N85 previously was working just fine (giving priority to cellular connections over data connections).. N900 not doing the same

Hi all. I have the same problem in Romania. I am on vodafone network.
It's really annoying especially with this crappy battery that n900 have.
I had a lot of phone mostly nokia that had a setting that was called "call waiting" witch applies also for data services.
Last phone was nokia e51 and it was switched on a 2g. I had an application that was sync my mail in real time an a messenger app also in real time.
I never had any problem with receiving calls on that phone.
Really if there's anyone who can make something for solving this problem, please DO.
Can someone make a bug report and asking for a call waiting also available for data services? I could do it but i don't know how...
I really can't stand it anymore, to charge my phone every night and next day around 7 PM is off.
regards...

Damn, I knew I should have went with Vodafone. The T-mobile deal I got had the same contract as the Vodafone one, but £100 cheaper for the phone, so technically, I saved £100, and lost the ability to browse on 2G in case I get a call. 3G is not great in my area, so this is bad news!

im on the network 02 and Im having this problem. After reading this thread, it seems that Orange, Tmobile and 02 are affected yet voda isnt? that can't be right surely?
I somehow don't think that this is a network fault.

well, my phone contract is via Carphone Warehouse, but Voda is the carrier. Maybe I'm just lucky (or there is some flaw in my tests)? Any other voda users care to repeat my test - still (just) time for me to place a big bet on the Brazil-Ireland game if I turn out to be blessed :-)

I have the same issue in NZ on 3G or 3.5G while using data. Several times have received voicemail messages much later. It doesn't seem to be confined to 2G only.

Also - the same thing never happened on my N97, so I think it is phone related.

On 2G I believe it is network dependent. Within a network it could also be tower dependent. Call volume will change how the tower allocates slots.

Would you happen to know what network they were on? I only know one person that's tried calling me while I was using the 2g connection and they were on Sprint.
