hmmm, i'm gonna say no. not unless there is a way to make it think it's an ipod touch...or to make the software use the email instead of phone number to call out... honestly not too sure. most people who have the iphone 4 use it with a network so this wouldn't be in high demand...but you always have a few that just want it to use on wifi.
 
just thought it was iphone uses just phone numbers and ipod touch and mac use email. means having 2 different logins for iphone and mac
