Another option would be Virgin Mobile:

These now have data plans for around $70 per month if you'd need that.
Security? If you want to be as anonymous as possible I'd suggest the following:
- Go to a place that has a "community" PC, like a library or other place when activating it
- Use a name like "Holly Hobby" or whatever
- List the address of a hotel or other business place
- Pay cash for "load minutes" - Radio Shack, Walmart, etc.
