The "refresh icon" shows your device is synchronizing something.
Check the setting on how often your gmail is set to.
Don't save into the "phone memory", that's your RAM, you'll need as much space as possible over there for your device to run smoothly.
The other one should be 16GB internal memory, save it there will not cause any problem.
You don't have any external memory card?

You ment 6GM memory, not 16, I think! No, I should buy a card... I have the phone as I took it out of the box! I don't think is possible to save something into the phone memory. But if it should stay so, the better! I will go and buy an external SD.
So the "synchronizing" part is when the phone is checking from time to time my Gmail account (if I recieved new mail) or Yahoo (I also installed yahoo), right?
I checked my options and it's set to 4 days, but that's strange, because if I send myself a test mail, in ~30 min I recieve a notification!
