yeah 1 year basic warranty, you can also buy best buy's protection plan on it, which i don't know how they work for the phones, but i've bought them on game controllers and the plans are amazing.
I've had 2 rock band guitars break, and both times i just walked into best buy, said hey it broke, and walked out with a brand new guitar 15 minutes later. Same for a regular xbox controller and a bluetooth headset.
Can't say it'll be 100% the same with the phones but should be similar, it also helps that i'm a premier silver reward zone member lol
