Hmm.. Might want to consider checking your post for errors before submitting it.. US Cellular is in there, like, twice? ^__^
And I do not care about typos to much, but they're within the names of the poll itself? (The '0' instead of a ')' for AT&T)
Ohh, and maybe a 'catchall variable/ carrier' would be nice, like, say, 'other'. Just in case you missed a few carriers.
Well, that's just me giving some constructive feedback, no bashing intended.
EDIT: Ohh, and I'm Dutch, but I'm seriously considering the iPhone. The prices seem pretty decent over here, starting at €30/ Month
