A recent problem started occuring on my 8125. Whenever I have direct push enabled and I connect with wifi it works fine until it needs to connect to the exchange server. it uses my edge connection to sync with server (it actually initiates a data connection to do this. if it is downloading a large email it will then freeze the whole device forcing me to restart. it never did this before, I haven't changed settings (i rechecked them), and I haven't loaded new software. Any ideas?
