JemJem offers the refurbished Unlocked Apple iPhone 4 16GB Smartphone in Black, model no. MC318LL/A, for $125. Coupon code "iPhone4deal" cuts it to $115. With free shipping, that's $155 under the lowest total price we could find for a new one, although we saw a refurb for $15 less in December. Deal ends March 6.
A 90-day JemJem warranty applies.
