Service Provider Phones?! Grr!

I use cricket as my mobile service, if anyone is not famliar with them a little something.


With my package:($57/month)
They have unlimited minutes all the time, unlimited text & picture message,caller ID, free long distance, some other things.

Well the only problem I EVER have with them is their phone prices!, let alone the small selection.

I was wondering if anyone can help me with a questions here.


Do you think they will let me purchase a phone, one they support already, from somewhere else and have them program it to use Cricket?

Unlocked or locked, I don't know if this applies to all phones or not but I know if it is locked they can't.


Do you know of any service providers ever allowing this?

Thanks

Cricket , isnt that a game.. sorry dude, no idea about this,
