I bought a perfect 16MB on 14 Feb for $475. Would not have bought off Ebay - On a Bet. Too many horror stories about getting blocks of wood, Paypal chargebacks, etc. Going non-contract ATT 'till the i5 ..or better comes out. I am in the middle of Verizon country (legacy carrier) but cannot get service at my home. I can use both an iPad and the i4 with an antenna on my roof. Both work fine on ATT. I kicked out the Verizon wire - they would not even give us DSL.
A cheapo-Nano phone would make me look foolish. 'Been there before...?!
