Blackberry Curve signal?!?

Question

It's been days and it hasn't gone back to EDGE even when I go in the spots where i had good signal.

How do I get it off GSM?

Answer 1

If the above doesn't work try taking it to your wireless carrier's store and have them try to replace the SIM card to see if that makes a difference, or use someone else's SIM card as a test.

Answer 2

Try powering off.  Remove the battery and sim then put everything back, then power on.  See what happens!
