The iSmash website advertises that they deal with water damaged iphones so I took my 12 yr olds iphone to the iSmash store in Guildford after it had been dropped down toilet. Was charged £20 for what is described on their website as "diagnostic test which will show them what component has been damaged". I explained I could not get it to switch on. An hour after I paid the £20 I got a call and email to say they could not repair the phone as it was a logic board issue and they could not do this. (Their website also says they repair logic boards!). When asked specifically what was wrong with the logic board the guy said he didn't know as the phone wouldn't switch on! I had told him this at outset. Was ripped off £20. If you have a smashed screen they seem ok but don't bother if it's water damage. Should be reported to trading standards
