Like above, make sure you're on .148 and give tech support a call.  If there's an issue they can't fix on the phone, they'll send you a replacement.  If you keep experiencing problems, keep calling them... on the third time they have to replace the phone, they'll send you a different, but comparable, device.

That said... I really don't have many issues with my Storm.  It crashes occasionally, but name me a PDA/Smartphone/BB that DOESN'T do that.
