I don't even know what to say....... I have had my DX for almost 2 years now without a single issue of the sort your experiencing of any kind. I must clairify that I am an Auto Mechanic by trade, and I keep it in my front pocket alot of the day, and it gets subjected to bumps, drops, sweat, dirt, 110+ degree temps in our shop this summer. (Kansas) I have always kept a good quality case on the phone at all times. I have never broken or even scratched the screen. (No screen protector) Its a damn good phone, Or - I have been really really lucky??? Should say No problems.... Until this latest OTA Gingerbread update. I had that OS on the phone for just over a week, and thats all I could take of it. It took a beautiful phone and made it a messed up POS. It was freezing up, dropping calls, not sending text messages, eating up the battery, and not able to send out calls, it even messed with the swype keyboard - made it all jurky and messed with the sensitivity of the screen. It would take multi touches of the space bar to get it to make a space? It would keep acting this way untill the phone was re-booted. Then It would act okay for a while (sometimes a day or two). It would eventually start acting like that again? So when I needed to make a call I would have to re-boot the phone. Good thing I didn't have an emergency!!! So this weekend I flashed 2.2.340 Froyo back on the phone, re-rooted it (Z4 Root), then used "SystemApp Freezer" to freeze the /system/app/BlurUpdater.apk. That will keep the OTA Gingerbread from pushing though again, and get rid of the Update warning message. Personally I like Froyo, it works fine. You can root it - it stays rooted. There are tons of Roms for it.
Do you think its possible that good old Verizon does stuff like this just to frustrate people into upgrading to a new phone. Just like automakers engineer things into their cars that make them expensive nightmares to reapir as they get older making it more attractive to just buy a new car - instead of fixing the old one?
