A recent survey [PDF] of cellphone users revealed that more than half of Verizon's customer base would abandon their current phones for an iPhone if given the opportunity.

Market research firm ChangeWave polled more than 4,000 cellphone users for the study. Of the Verizon customers surveyed, 19% said they would "very likely" purchase an iPhone if it became available on Verizon, while another 34% claimed that they would be "somewhat likely" to purchase.

Sprint and T-Mobile customers were less enthusiastic about the device. 11% of of Sprint and T-Mobile customers said they would "very likely" buy the iPhone if it became available via their carrier, and only 33% and 28% said they would be "somewhat likely" to buy, respectively.

"The survey results show an unprecedented level of pent up demand for the iPhone among Verizon subscribers," the survey noted. "If Verizon were ever to offer the iPhone… [it would have] a profound and likely transformational impact on the industry."

Although many Verizon customers want an iPhone, very few are willing to switch to AT&T to get it. 49% of Verizon customers — the highest in the industry — claimed that they were "very satisfied" with the carrier. Furthermore, only 7% said they were "very likely" or "somewhat likely" to switch wireless providers in the next 90 days, compared to 8% of AT&T, 10% of Sprint and 14% of T-Mobile subscribers.

The study again leaves us asking: When will the iPhone come to Verizon?
