Hey Guys, wanted to share how I’m setting up my phone for the PCT.

1) deactivated iPhone 4s upgraded to the latest iOS

To save money I decided to not buy a service plan. Wireless service providers are required by the FCC to allow non subscribers access to the network when in an emergency. My deactivated phone calls 911 just like anyone else’s phone, provided there is a signal. The iPhone 4s also has a built in GPS that hiking apps can access for positioning data without needing a dongle, again no service plan or even cell signal required. And with the built in wifi whenever I’m around a hot spot the iPhone easily turns into a fully functioning internet phone after adding a couple of apps.

2)Install Google voice

Google voice offers a ton of telephonic services, I’ve installed the phone app to do one amazing thing, send and receive SMS text messages for free! Do note images are not supported and no notification will be sent if someone sends you an image.

3)Install Google Hangouts

Google Hangout adds more features over the basic google voice app and also supports text messages, but when SMS is enabled on hangouts limitations are placed on the web service. I install both apps to keep all options available when using google voice in the browser. Now this is the kicker, the main reason to install Hangouts is to make and receive domestic calls in the U.S. for FREE! Yep, google is giving out free internet phone service when using this app. What this means is you get free cell service when wifi is available, simply awesome!

4)Guthook’s PCT App

Read a review over at Joe Brewer’s Blog and after using the demo agreed that Guthook’s PCT guide was the GPS mapping and trail data app to go with.

5)Halfmile’s

Standard Halfmile’s PCT app, good free backup.

All in all I am very confident in what this setup will provide on trail, but to have a physical backup I’m also bringing a copy of the Pocket PCT Elevation and Data Guide

I’d like to hear y’alls suggestions or recommendations for making any improvements. Thanks

I carried an iPhone 4 on my pct thru hike also. I did the "sim lock" method and if you don't enter your sim code when powering on your phone the it doesn't use cell service but still allows GPS to function. It lasted up to 6 days if used sparingly. It was my camera, my way to communicate with people back home, and oh so much more. I loved guthooks. It never really let me down. It was probably one of the most amazing apps for the PCT and one I reccomend 1000000%

Thanks Richard for the tip, I might tryout the sim lock trick on this one too. Though I'm still not completely sure if this phone uses any battery life or not to search for signal, being it's not activated.

Thanks Amy, good link and will do. It's hard to imagine why version 4 beats out 5 on battery life by so much. 1-2% per day vs 10% per hour is a really huge difference.

"1-2% per day vs 10% per hour is a really huge difference"

To clarify for people who haven't read the full article — That egregious iPhone 5 battery drain bug is limited to the ATT model, and only occurs when you have no signal AND have either removed the SIM or locked the SIM. And if you leave the SIM enabled, then the baseline drain is ~10% per day instead of ~10% per hour. The Verizon phone does not share the problem, and the ATT iPhone 4 does not have the bug. I don't know of anyone who's done structured battery drain testing on the six or six plus, ATT or otherwise.
