When it came time for a new phone, I skipped the 4g in exchange for a phone that was water proof, and damn near indestructible. I picked up the Casio Commando and havent had any issues. I throw it in my Chrome holder attached to my Seagull bag strap and use Endomondo and it tracks fine. When I first got the phone, I bought a handlebar mount that failed while going about 25-30 down a gravel road. The phone barely had a scratch and the screen was perfect.
