hey gang,
I was wondering which cell phone is the best phone to use for moving bitcoin?
I recently purchased some coin, took a picture of the receipt and tried to attach to email but couldn't. pretty sure it's the iphone because I couldn't upload the picture via iphone email client or when going to the email website on my iphone, either. had to wait until I got back home to use desktop pc. also, I can't find an app for the iphone that will allow me to send coin. so I'm thinking it's probably the iphone.
any suggestions on which cell phone is best for bitcoin transfers and which app? heavens, when is someone going to invent the bitcoin phone,

!
appreciate all your help.
