What if I tell AT&T wireless to bite off and migrate my phone number to Cingular, then they merge? (For those not around here, the law was changed recently so you can keep your phone number when you change vendors. Funnily enough, hardly anyone has done it so far. It may become more prevalent in the future). They have to make the change with a time granularity less than a billing cycle.

It's not even that far off of reality. After falling for a $75 bribe to switch to AT&T long distance for my business line, followed by ridiculous rate increases, I switched elsewhere and vowed not to do business with them again. Within a few months, AT&T bought my wireless provider. And made me switch to a lousier multiplexing format. Dammit. But now they aren't AT&T anymore... are they?
