I've tried taking the battery and SIM out and restarting.

Any ideas?

Note I had my T-Mobile SIM in the BB for the entire process.
My solution so far has been to downgrade to 4.2. Under 4.1, my T-Mobile SIM worked just fine. Under 4.2, it works fine, but if I power it down, the only way to avoid an "initialization failed" message on restart is to remove and reinsert the battery (an AT&T SIM handles this OK). Under 4.5, I get the initialization failed error message all the time with the T-Mobile SIM, even if I remove and reinsert the battery.
