Hmm, wish I had seen Castro's adivce yesterday. I took my phone to orange shop at Basel SBB, who were actually very helpful. They said all iphones have a one year guarantee but said I would be better taking my phone to the mobilezone shope where I bought the contract as they could replace my phone for free rather than the 50chf orange charge.
So off to mobilezone -they were really difficult - they took the phone and said they would send it to orange and it could be returned or replaced in between one and three weeks. They could then SMS me when it arrives (on what?). I tried to ask if I would have to pay anything, but they would not answer me directly and said it depended on if the phone was broken?? They just shrugged their shoulders when I told them about the iphone one year gaurantee.
Makes me want to run back to the mobilezone shop to see if they still have my phione so I can grab it back and take it to zurich!
