I phone problems?

Question

I have an i phone that I purchased in Seattle in the summer

More recently it keeps getting stuck, cant receive calls, or use the phone

I dont know where I kept the bill of sales,

can I still return it, It should still be under warrantly

Answer 1

you need the bill of sale as a proof of purchase. you can have it checked on a phone center stall

Answer 2

I'm probably wrong as usual, but I'd say next time don't buy a $20- phone.
