Great bike ride today, unfortunately my Nexus 7 phone went flying and didn't survive. ;-(

I figure this is an omen that I should buy a new unlocked T-Mobile iPhone next Friday, but in the meantime I need a cheap backup I can order from Amazon for next week.

All I need to be able to do with it is make phone calls, check email and use maps.

I'd like to pop the SIM out of the old phone and put it into the new one.

Any recommendations?

Update: I remembered I have a Nokia Windows Phone here that works with T-Mobile. Charging it up now. I wonder if I can remember how to use it well enough to get going.
