I have had this phone for 18 months now (getting close to getting an upgrade wooo), and I am ok with it. inevitably, while the phone was new and exciting 18 months ago, it's now alarmingly out of date and highly frustrating.
My number one issue with the phone is its touch reception (if that is the right wording). When I used to type with buttons I could write a long message extremely quickly. However now I constantly have to go back and amend any errors made. This is after 18 months so it is not used to me being unused to touch screen, it is the fact that it constantly seems to struggle.
It was however bought on a very cheap deal where the phone came free, and now the deal would probably be even greater. I wouldn't recommend unless you get the contract very cheap, but just remember i got this almost 2 years ago on a great deal, i'm sure you could get much greater now (i pay £15 a month)
