Should delete that 0, then it'll work.

As for the apn thing, I've never heard of that one; I'm using wap.voicestream.net (or something close to that; wap.something, anyway) which is the default and works correctly.

A quick google shows some references to that WRT prepaid plans, apparently they get unlimited data that way, and also it's apparently being shutdown in some areas. I might have to try it out, but I know the wap.*.* that the N8x0 defaults to works.
