Hi, I noticed my phone has a tendency to drop calls when switching from HSDPA to 3G. My phone dropped calls about 5 times today, so I thought I'd do a little test... I rang someone (display showing 3G) then refreshed my GoogleMail app (display went to H) to see if the call stayed connected... well... it dropped the call. I did the exact same thing again... dropped the call. I tried this about 5 or 6 times using different apps to basically put my phone in HSDPA mode and it is dropping the call when switching between 3G and HSDPA... Is anyone else having this problem? I am on 3, UK Tom p.s. my fix for the moment is to disable all background data updates so hopefully the phone will not try accessing the internet whilst i'm on a call.
