My phone's sufficiently programmable that there's some interesting location based applications I'm tempted to play with, but to make that work I need to more consistently carry my mobile phone around.
I was tempted by the belt clip, but my girlfriend seems to be of the opinion that is some sort of massive fashion faux pas. The simplest answer "in your pocket" also has problems because most womens pants have sucky pockets.
(What I wish would be that Scott EVest would make some of their hidden cargo pants in womens sizes.)
How do you prefer to carry your mobile phone around?
If you carry your phone in some sort of bag, how often do you carry that bag with you? (1 almost never, 5 always)
