:DI do not even attempt to keep up with the latest in electronics and cell phones. My cell phone is okay for talking and makes pictures, what more could you want? I discover what more I could ask for, waterproofing. I fished with a new acquaintance Sunday afternoon who had a submersible phone. He had dropped in a lake and found it at night by calling it and seeing it light up underwater. He was using Verizon and I did not get the model and make. It was a little clunky but not that much. I have a friend in south Mississippi who has a Motorola Quantico, which is guaranteed for up to 3 ft. underwater for 30 minutes. It?s good to see that those of us who sometimes get wetter than we meant to have not be forgotten.

I have this one from Verizon. Even though it is good to 9ft I put a lanyard on it and attach it to my vest. Don’t think I want to be diving for it in the current. Very nice phone for fishing. The mini chip holds a couple hundred photos so your not having to empty the phone all the time.

I’ve went through this same buying decision making process. I look at the high price of the phones, the much larger size, and the lack of cell phone coverage is most of the places that I fish and I have passed on these types of phones in the past. I think as cell phone towers continue to cover more areas and the phones and prices follow they will begin to attract more fisherman. Until that happens a zip lock bag suits me just fine.
I would encourage you to upgrade from the ziplock. My old fishing buddy was using that with his company Blackberry only to have it ruined in the outer pocket on his neoprene waders. He was a SVP with the company and got away with it without too much grief. I am just hoping my carrier will have one of these “guy phones” (with apologies to the ladies) when we redo our contract. My last phone didn’t die in the water but on the concrete, I need a phone with a name like Quantico. I am using a donated Slvr now that is just too small. I know the Quantico also has GPS capabilities if desired.
if you need a secure line to talk to the POTUS, get this one

heres some “manly” phones
My cell carrier has a couple of ruggedized phones but they are too bulky for every day use. When on the water, I keep my personal Blackberry in a Pelican 1010 Micro Case. Cost about $15. It holds many different phones and there is a slightly larger size too. Not waterproof like the larger Pelican cases but it is very water resistant and if dunked will keep the water out long enough for a fairly quick retrieval. It also floats. When I have to carry both my personal and work phones, the personal phone goes in the case;)
Phones that have GPS, take photos & allow you to do postings on the internet and share photos, can cause you grief if your posting gets into the hands of the wrong type computer geek/hacker. The photo carries the GPS signal of latitude and longitude.
So if you post a picture of your cabin, and say that you will not be returning until late September to close it down for the winter, you can bet that the place will be broken into…

I have a old cell phone, that I got when I was on the road at night as a contract delievrey business, as a lifeline. Now I discontinued my service, but I keep it charged and in the vehicle. Even if you are not subscribed carrier, if you find yourself in trouble, and nobody is sight, the 911 still works!!!
DryPak and Aquaseal both make totally waterproof bags to fit cell phones and cameras. I have the DryPak bags for camera and phone. Both, when tested underwater, without the phone or camera but with a piece of brown paper bag, withstood their stated waterproof depth. Both bags float, have a bright yellow plastic sealing tab as well as a lanyard. If you Google the brands, you should be able to determine which you’d like. DryPak is less expensive which is why I chose it. Am happy with the bags after I learned the hard way that ZipLock doesn’t work to waterproof a cell phone, even in a light rain in a GoreTex wading jacket flapped pocket. Amazing, but true 
BTW, my DryPak camera bag is supposed to have what they call an “optically correct” vinyl though which you can shoot photos without taking your camera from its bag.
I have the casio g’zone phone mentioned after getting my last phone wet on my boat----it tough and water-resistant but for my old eyes, the numbers and script are waaaay too small even in LARGE mode----and is difficult to see anything on the screen in sunlight.—otherwise, i have no complaints.
This may be of help.
I fell yesterday in the Gallatin while trying out my new G4 boots. I was thoroughly soaked but unhurt and nothing was broken. I did not realize I had my phone in my pocket until I got back to camp and was putting on dry clothes.
The phone (an LG) was completely dead. Nothing came on at all. I took the phone to the Mall in Bozeman and asked the lady at the Verizon kiosk what I could do to save it. (I was more concerned about the numbers and addresses than the phone not working). She told me to buy some white rice, disassamble the phone and burry the the parts in the rice for at least 24 hours.
I followed her advise and today the phone worked just fine but I think the battery is toast since the phone will only work while attached to the charger.
PS I don’t think my new boots caused my fall but I am screwing in studs before going back to the river in the morning.
This saved my iPhone, too, even though I couldn’t open the phone up any. I just buried the phone in the rice and left it for about 36 hours.
Aquaseal was a Sponsor here for several years until the waterproof cameras made it unprofitable…good products, good people.
