A lot of people believe these two phones are the exactly the same.
While they are similar, there are a few differences; for instance the S620 is slightly heavier and longer and maybe a tincy wincy bit wider than the Dash. Also the face plate is slighty differet because of the extra wide-ness of the S620.
The other difference from the Dash when compared to the S620 is the volume strip, on the S620 there is a messaging along with a back button.
The S620 also lacks a design flaw that is present in the t-mobile dash. Due to the sensativity in the volume strip on the dash, users may have problems with call waiting.
Example of the problem:
You are talking with someone and you’re phone beeps to alertyou that there is an incoming call, if you touch the volume strip the person you are talking to is disconnected and you are imediately connected to the incoming call regardless if you wanted to accept it or not. The only work around currently is to disable the volume strip.
The above problem is not present in the S620 as I have tried and tried again to duplicate the problem. T-mobile is aware of the problem in the Dash and is hoping a software upgrad they are working on will rectify the problem.
Aside from the size and the volume strip the Dash and the S620 are identical.
OH yeah forgot this, the keyboard on the S620 is similar to a keypad is different, mainly just the alt keys and the volume control on the s620 is better.
