So I'd read about Ubercab in one of Tofu's recent FR's, i.e. a private car service that you can access from your phone with a few minutes notice if you are a member.

This would seem to hold considerable benefit for those of us concerned with logistics, bouncing, and generally looking like bosses.

What other apps/etc do people use that they think are useful in these sorts of pursuits? I'm NOT talking about apps that are collections of pickup lines or shit like that, I mean useful tools in the field, similar to Ubercab.

Setting your convenience key to "contacts" on Blackberries and some other phones can make you quicker on the draw to get numbers, I suppose.

I know people sometimes use fake dialers/etc to simulate getting a phone call, and I'm sure people are also using much sneakier shit that we'd all love to hear about.

Edify me.

EDIT: I'm NOT talking about Bluesnarfing girls' phones so you can cold-read them better or shady shit like that, nothing illegal.
