USPS package doesn't arrive?

USP problem. Hi I made a purchase from eBay on December 13 and was sent to my address in Maryland the same day but it's 20 and im not received my package, ebay providedme a tracking number they said the package was shipped on the 13th from Louisiana and came to Nort Carolina 15 but from there the package is not updated in the tracking number, the package is a iPhone 5s and the package is with 50$ of insurance, 2 day shipping.

My iPhone 5s screen is uncalibrated?

My iPhone 5s has been working beautifully since I got it last month, but this morning I woke up, picked it up and noticed the screen was all uncalibrated and blurred with a greyish tint. Some parts of the screen work but I can't click on any app or scroll or anything like that without it being complete luck. Everything else is fine as far as I know, including the fingerprint scanner. I never dropped it yesterday, and it's never fallen more than 2 feet lightly. I also didn't set it in anything when I went to sleep. I am wondering what could have caused this and how I could go about getting it fixed. Also note I cannot shut it off and turn it on because the slide to power off button is on the screen and. Well, you know.

My Iphone gets submerged in water?

Hey guys…
Well it happened like this. I went down from my hotel in Bali to the beach with my iphone 4 in my pocket. Then i swam into the water with my phone in my pocket and played with my sister going out and in the water (that sounded weird) but no matter, it lasted for like 15 minutes.
After that i finally found out that my phone had been in the sea water for that whole time!
I panicked and tried to turn it off…(found out it was a bad move) and then I ran to the hotel's kitchen asking for rice (got that idea from my sister) i put in a plastic bag since i had to return back to my home country right after the beach adventure…
when i got back home the next day, i placed my phone in a electronic drybox and left it there for 5 days until today. Today i recently tried to turn it on by charging it… It didnt turn on after 30 seconds,
i decided to put it in a bowl of rice+place it in the electronic drybox… Like just now…
I am worried sick…
Please help…
will i ever see my phone come back to life again?
Please Help ANY OF YOU! Its five days since the submerged iphone incident…
