<p>my service provider is cingular, but i've heard that verizon is the only viable option at cornell.
would i have to get a new phone?</p>
<p>You don't have to, but i would highly advise it if you can. Cingular's service is very spotty and you will almost certainly have to go outside or near a window to make calls. But if you don't plan on using your cellphone too often maybe that won't bother you.</p>
<p>it probably won't work in any buildings</p>
