OK, don't know what market you're in (t-mo with 2.2.1 or other with 2.2.2) but regardless, try this first:

1) Open your dialer (the one built into the phone)
2) Type in *#*#4636#*#* (this takes you in to the INFO/TESTING menu)
3) Select "phone information"
4) Scroll down to "set preferred network type".
5) If the choice is "GSM only" change it to "GSM auto (prl)". See if that helps. Does your phone have wifi-calling BTW?
