For rent- Samsung Galaxy Fit. I have recently upgraded.
Phone is unlocked, was previously a happy little pre-paid on Vodafone network.
Comes with charger. Be good for someone who may be Apple but needs to test their App on the Android market place or backpacker who is visiting and just wants to be able to buy a sim and have a phone without the hassle of contracts.
It's 2nd hand so it isn't scratch free on the back but it works, the screen is fine and charge is included.
