Sony Ericsson K790i — Mobile

When my elder son bought a Sony Ericsson K790i in Oxford, it seemed a bright buy since it cut away the need to manage a separate camera...ideal for a student who likes travelling. Subsequently, I bought the same set for my younger son here in India this January. This piece has been non-functional longer than than it has been o[censored]se...all the keys had become sluggish and some non-functional. Now it's been sitting at the service centre on its second stint for the past fortnight almost. The result is I have been without a mobile all this while. Even now, some parts have not been located. Since this is the second time, back to back, that the instrument has gone to the centre, I think there is something seriously wrong with the model and I do need a phone immediately. I request Sony Ericsson to replace this with a more dependable model...if there is one. That there is something wrong with this model is quite clear because my elder son's phone has also packed up as a result of 'water vapour' formation...from the air!!! This too is absolutely untenable. Sony Ericsson thus is doubly responsible for these two unhappy rides that two trusting customers have been taken on.Looking for a sound and quick redressal.
