TechForensics's Journal: Verizon Wireless blocking Google Directory Assistance

It seems that Verizon likes to enhance revenue by making sure their cellphone users have to use Verizon's fee-per-call directory assistance service. A number of times over the past month I have tried to send a text message to 46645 (googl) with a name and address. Normally this gets you a text message back with the phone listing for about five cents. Lately text messages to this number simply don't work. Anyone else with similar experience?
