every time i go off wifi an back onto EDGE i need to log in to t-mobile and resend my service books and remove battery for 30 seconds otherwise i can not get any emails
i can send and people receive what i send them but any emails sent to me do not show up until i resend the service books
this happens every time i go of wifi

i would just not use wifi however my house does not get good reception and it is my only choice

any advice?

Try reloading the OS to see if that helps...if not wipe with JL Cmd and then reload the OS...never had that problem when I switch from Wifi to EDGE/GPRS on my Curve
