Simple little flip phone, no worries about butt-dialing. It'll take pictures, connect to the internet, text, play a few rudimentary games--and I don't do any of that. It's a phone, for heavens' sake! I don't like receiving texts and won't send them. I have illness in my family, so when I'm away from home I usually forward the land line to the cell, but the phone is for emergencies. I won't talk on it when driving, much less answer a text.
Like others here, I wear shorts, mainly cargo type, this time of year. Phone goes in the cargo pocket or dedicated cell phone pocket. Otherwise shirt pocket or off-side pants pocket with the knife and keys and rescue inhaler--the holstered J-frame is in the right pocket. I have done the trick of carrying two speed strips in a cell phone case, adding a little flat Gerber lock-back knife. It works well.
