I had a problem with my 6500 Slide with 3, it would randomly not know what MP3's it was playing and say if i moved the phone or changed the volume it would do the same, also it would freeze and could'nt use the phone.
I got a new replacement after ringing 3, they tried to fob me off by asking did i want it repaired but i said i would like a replacement so thats what they gave as they said ti was within 14 days of having it.
I did go into store and ask how long is the standard warrranty on the phone before taking out the contract and they said its 12 months manufacturers which just covers the phone becomes faulty aslong its not caused by the users.
I do love this phone though even though i would have loved to of had he N95, takes some great pictures given the lighting is ok and is a great MP3 player to, has loads of neat feature that i think are just awsome like being able to answer it with one button and hearing the person through my car speakers and still being able to hear me talking to them.
