It makes sense for Apple: Analysts say iPhone sales could as much as double as a result of pursuing broader carrier distribution. Plus, it would help assuage the concerns of the Justice Department, who have indicated trepidation over iPhone exclusivity with AT&T.
It even makes sense for AT&T, who in some ways are arguably shouldering an excessive burden by being the sole carrier of the data-intensive device. Many of the customer complaints about AT&T's service (or lack thereof) can be traced to network troubles that are primarily a result of the bandwidth-hungry Apple phone.
So now rumor has it that at least one of the other three U.S. carriers may add the iPhone to its roster next week. The inside sources that conveyed the news didn't disclose any details about which carrier that might be, but earlier rumors point to Verizon as a likely candidate.
