Samsung S3650 Corby is a very fresh looking handset too – distinct shape and bold paintjobs. It won’t really make much sense in adult hands but the Fashion Jackets – bright-colored interchangeable rear covers – are perhaps as strong a selling point as the capacitive touchscreen. There’re two extra Jackets in the retail box to make the time spent with the S3650 Corby even more personal experience.
