The w910i I thought was one of the best phones of ericsson unfortunatley its been only 2 months since my purchase and I have been having endless problems with it. Firstly the handset starts getting heated in 5 min on a call I have almost visted the service centre 4 times and all they do is software upgrade which does not work the call centre as well as the service centre is inefficent.
I have been having endless problems if you are on a call for half an hour u cannot hold the phone but nothing is done to rectify it. Such an expensive phone and it is such a shame the service centre maintains that such heating is normal imagine!! u buy an expensive piece and you are told that heating of handset is normal . further it has battery problems you have to keep charging it twice a day. So overall the phone is a NO and above all recommendation by me is SONY ERICSSON itself is a big NO.
