Had mine for three months and I'm really pleased, replaced my N95 8gb which I had for over a year and although I'm not keen on apple it is very slick!
Although my N95 actually did more, can you believe you can't forward a text message on an iphone? The version 3 firmware release out in the next month or so which will give copy and paste and MMS and a lot of other stuff so it'll hopefully get a lot better. Did you know you can actually buy a totally legit sim free/ unlocked iphone 3G, not cheap though £599.99.
By the way a lot of beta testers for version 3 have been pulling the code to bits and apparently there are hints of a new hardware version buried in there?
