Can I use an at&t iPhone with Verizon?

Hi- So my friend gave me her old iPhone 4, but it's with at&t and I have Verizon… Is there a way I can get it to work with Verizon?

Unfortunately, you can't use the AT&T iPhone with the Verizon network because the AT&T iPhone uses GSM bands while Verizon uses an older standard known as CDMA to operate their phones. Hope this helped.

Nope.AT&T is GSM & Verizon is CDMA. Don't work with one another.
