Which iPhone Apps have you found to be the most relied upon?

Amazon, Facebook, Foursquare, Gowalla, Pulse, Kindle, Pandora, Photoshop Express, Grocery IQ, Bump, Starbucks, Skype, Walgreens, Dictionary, AED, Flixster, YouTube, Calvetica

ByteSMS, can’t text without it.

MyWy, I’m grandfathered into an unlimited data plan so this is essential.

LockMS with the weather mod.

Orb, streams music from my home computer to my phone.

Callinfofields, essential when you want to know what number is calling you when someone calls.

Led light activator, turns you iPhone 4 into a flashlight when you double click the sleep/wake button

Facebook

Awesome solitaire

Skype

Things, great GTD app when paired with desktop version.

Billings, for my desktop invoicing app.

I don’t really rely on any but the ones I use the most are probably Facebook and Bubble Shooter. Both are good boredom cures!

Skype is the most useful in terms of practicality.

I don’t have an iPhone but I have an iPad and I use some iPhone apps on it. If you’re looking for a fun game, look for Carnivores or Zombie Infection. I think they have free trials and they’re really fun.

Whrrl, TriOut, Vodafone Update, Instagram, Appsfire, Foursquare, Tumblr.
