My Touch thinks it has a different number

[Binge]

When I ordered my HTC Touch, I planned to have my phone number ported from VZW. There was a big mess, and Sprint ended up having to give me a temporary phone number while VZW released my number.

Now I have the correct phone number, and calling and answering works perfectly. Except for the fact my phone internally still believes its the temp number.

I manually put in the Voicemail number, so that works correctly. But I cannot connect to anything Sprint related through the phone, since it errors on the phone number.

I have called Sprint about this twice, and both times they said its normal and it will fix itself. Even after I protested they just have no idea what I'm actually asking. I really don't want to have to talk to them ever again over the phone, since its always very painfull.

So I'm looking to see if anyone knows how I can manually change the number on the phone. Thanks!
