I too have been having too many issues for a device that should be more seamless. It needs a soft reset several times a day, the funny thing is when it does need a reset- it takes about 4 of them to finally take. There are screen errors and not all apps (PocketPlayer) in the menu load every time! I know I have the memory almost pegged, but still....!!
This is also my third replacement (Lemon law?) so I am anxiously awaiting the Omnia (but still leary of another Samsung turd) I was considering the BB Storm, but everyone at work (also hates their i760) uses a MS Exchange Server, so BB is out.
