This etsy offering gives your beloved iPhone somewhere to chill and charge. At $195, the iRetrofone Base isn't cheap, but it is handmade, sculpted and cast to order. You'll need to provide the Apple USB charger for charging and syncing, and this would look great with the an iPhone rotary app to complete the effect.
The iRetrofone iPhone Base is compatible with all Apple iPhones (except the leaked next generation model, which only affects Gizmodo and Apple employees) and the handset is advertised as a working feature. Alongside the handsome Bruce Wayne era black model are a clear base and pink princess themed models.
Note: these sold out while we were putting together the post just now, but seller recommends contacting them for additional orders.
