I bought an iphone 4 (verizon) from ebay?

And i was wondering if i unlock it, can i put my old phones chip thing in the new iphone? And would it work well? My old phone is t-mobile

I'm pretty sure verison doesn't have simcards… I might be wrong, though.

What i know about Verizon is its phones doesn't have sim slot, and it can only be used with the Verizon CDMA network in the US. I don't know about the Verizon Iphones.

if you're good with that, than cool, if not do what i did once, ship it back to the seller. And buy AT&T iphone, you could easliy factory unlock it from ebay for about $5.00:)

i just factory unlocked my Iphone 4 from them

sorry couldn't help you much!

Verizon phones are CDMA, and T-Mobile is GSM and not compatible.
