problem with unconnecting

[eddy]

In our family we have 3 mobilephones all SE. The problem is just with my phone-Thats the strange part. The Z550 and W850 does unconnect without problem, but not my K800.
I use MacOs X. In our laptop (pc) Vista it´s the same problem. And because of that it must be the phone itself or am I wrong? The W-phone has the same memorycard as my K-phone and when I switch cards It´s still my K800 that irritates. It´s so frustrating because with every attemt the antivirus apps in the computer also restarts and check for virus.....
