I recently changed my phone number with Sprint to get away from a stalker ex. The change was successful, but when I hit the 1 key for voicemail speed dial, it is still calling the old phone number and I get an error message. I tried editing it through the speed dial assignment menu, but the #1 is uneditable. I have to manually call the number, and do security checks, which is extremely annoying. Anyone know how to fix this?
