Now that the 4s is coming i am sure there will be a number of iPhone 4's available on crags list. I know sprint has a thing about not provisioning other carriers coma phones but will they be willing to do so for older VZW iPhone's? any sprint sales or csr's encouraged to reply please!
No the new iPhone 4 that is being release is 8 gig that's why they drop price to 99 and those will be carrier specific all previous CDMA Verizon iPhone 4 will still be locked to Verizon .. Esn on the phones will be locked to that carriers network even for the iPhones 4 on sprint
Sprint, does not allow you to use other carriers with their carrier, therefore unfortionely no.
Unless you found a way to take the Comm Board out of Verizon's iPhone 4, and put it in a Sprint iPhone 4, which is very unlikely.
