What time should I go to tmobile?

I live in a small town and tmobile opens at 8 am what time should I get there to get the iphone 6. There's also a verizon, sprint, AT&T, target, and a best buy across the street and apple is like 5 mins away! But I'm worrying if I will get the iphone 6 or not

I'm in the same situation. I'm thinking if it opens at 8am then get there at AT LEAST 7am. Get there at 6am if possible. I'm in the same worrying predecumant and I'm worried and nervous. Hope you get it and good luck! Wish me luck!
