I have had an iphone for about 6 months and without a doubt is the best phone ive ever had, very easy to use and has a lot of features and extra content to download easily. ive had no problems so far and really like it. i know people with the non S version and the speed difference is very noticeable so i would recommend the faster version. the only problems i would point out are the lack of an ability to customize much. It is very difficult to add custom ringtones, open attachments to emails (or to send anything other than a picture as an attachment) and not being able to set songs (even those bought through itunes) as ringtones does get irritating. Overall the phone is very powerful and stylish and i cant see myself swapping to any other brand in the near future even with the drawbacks (which will hopefully be fixed in the future.
