Buying iphone connected to a carrier for wifi As of right now I don't have a smartphone, but am debating getting one in the near future (although not sure in how long that will be.) My old itouch just broke, so i wanted to know if it is possible to buy an iphone off ebay, one that is connected to verizon (not unlocked) and use it with just wifi until I decide to add it to my network?
You need to be sure the iPhone is not blacklisted.

You can use Verizon site:

Depending on the iPhone model (CDMA or GSM) you need to enter MEID or IMEI code.
