Beware of Samsung smartphones!
I had a Samsung phone prior to switching. It came with Windows Mobile 6.1 (or 6.2). A lot of the features of the phone and features of the OS were crippled by Samsung rushing the phone to market. Things just didn't work or worked poorly. So what does Samsung do, they just move onto another model and stop advertising this one, which doesn't help the many thousands of owners that are stuck with a 2 year contract. When MS came out with an update to Windows Mobile 6.5, other manufacturers made it available to their customers for upgrades, but Samsung didn't. Overall I think Samsung makes pretty good products, but if you get one of their products that they took less care in manufacturing, they will forget about you and you are on your own.
