I bought my SIM free Desire last week, whilst travellig in Norway. Starting it up over here with my T Mobile SIM was no problem, but I have since noticed major dropouts of the network access (no signal), which I never had on my G2/Hero. It's the same SIM card, the same location, same contract, nothing has changed apart from the phone. It will do this every 5 minutes or so for a few seconds, but of course any call is cut off, and any message being composed will be lost. So far I have checked I have the latest software, and I have rebooted/hard reset the device. I haven't reinstalled any apps yet, apart from My Backup Pro, and reloaded all my SMS's. I have taken it to T Mobile asking if a new SIM was required, but they said no. Carphone Warehouse suggested flashing it, which I'd be reluctant to do, as the scandinavian software version has the dictionaries I need to use both languages easily. I have emailed HTC with no reply as yet, and am waiting for the shop in Norway to get back to me if they are able to let me exchange by post. Has anyone had to deal with HTC Global Warranty, and if so, does it sound like I will be covered to have HTC UK sort it out? It is a superb phone otherwise, am thrilled to bits with it, but it's not really capable of keeping calls at the moment! Any suggestions very gratefully received.
