I like carrying my cell phone when I ride on area greenways, just in case. But I'm wondering if the vibrations the phone is experiencing are likely to cause damage to it? And whether it matters whether I carry it in my jersey back pocket versus the underseat bag (which I prefer to use).

Anybody have any experience or opinions on this? :>

Back story: my phone seemed buzzy last night, after spending 16 miles lounging in my bike bag. I panicked that I had ruined it, but today it seems OK, so it was probably just poor line quality. But that's what got me (a) scared and (b) wondering.

My cell phone company offers insurance at $4.99 a month, but that adds up over time.

Thanks so much,
