Review: Samsung DoubleTime for AT&T
There's nothing inherently wrong with the Samsung DoubleTime. It's a fine phone in most respects. It's also completely boring. For a device that is obviously aimed at helping bridge the gap between quick messaging devices and mid-range smartphones, the DoubleTime offers few unique or interesting features.
It works well as a phone, battery life is good, apps perform well for the most part, and it can help get the old QMD user in the smartphone door.
For $50 it's hard to knock the DoubleTime for anything serious, and there's a significant lack of $50 QMDs available from AT&T at the moment. So, if an inexpensive smartphone with a keyboard is what you need, the DoubleTime certainly fits the bill.
