Other mobile platforms may be catching up, but there's no disputing that the iPhone has changed the way many of us live our lives and do our jobs. After reading TechCrunch's recent list of their most-used apps, we here at TechFlash HQ were inspired to share our picks, too. 

Let us know your favorites, especially if you think there are some undiscovered gems out there that could make our jobs or lives easier.

John's Top 5 Apps:

iRecorder: I've got four words for you: I LOVE THIS APP. A great tool for any journalist, iRecorder allows you to record interviews and then easily pause, fast forward and rewind. Higher quality recordings than my Olympus digital recorder. Amazing. No wonder Apple built this functionality into the new iPhone 3G S. ($3.99)

Urbanspoon

Urbanspoon/GoTime: Shake the phone: find a restaurant or a bar. Seattle classics, these restaurant and bar locators help my indecisive wife and I narrow our choices and get reviews on nearby eateries and taverns. Just looking for a cheap drink? GoTime offers the scoop on happy hours at Seattle watering holes. (Free)

ShoZu: I take photos now with my phone almost exclusively. ShoZu solves a real problem -- moving those photos from the phone to social media sites such as Twitter and Flickr. It's not perfect, but it works. ($4.99)

Pandora: I stopped listening to music for a number of years. Pandora -- with my personalized stations for Iron & Wine, The Kinks and The Stone Roses -- is making me a fan of music again. I just wish you could check email or browse the Web while this app was running in the background. (Free)

TwitterFon

TwitterFon:  Simple and easy to use, TwitterFon may not be the best Twitter app out there but it works for me when I need to post updates on the go or check the buzz in the startup community. Probably my most frequently used app. (Free)

Todd's Top 5 Apps:

Pandora and TwitterFon are also among my most frequently used apps, and I'm going to take a second look at iRecorder based on John's endorsement above. I crave the full-featured MLB.com At Bat 2009 (not just the "lite" version) but can't justify the $9.99 price tag. Apart from those, and Facebook's mobile app, there are several others I would have trouble living without.

Seattle Bus: As a public transit rider, I use this app all the time to figure out when the next bus will arrive. It shows scheduled and actual expected arrival times. The functionality is not perfect, but more often than not, it's accurate within a couple minutes. ($4.99)

Shazam: The app that will amaze your friends and turn you into the Alpha Geek of the evening as you subtly press a button and inform them that, yes, in fact, that is Miley Cyrus playing on the dive-bar jukebox, and maybe it's time to leave. (Free)

Public Radio Tuner: Lets you listen to your favorite public radio station on your iPhone, streaming over 3G or wifi. One of my new favorites, this is another app, like Pandora, that would benefit if Apple upgrades the iPhone to allow third-party apps to run in the background, letting people listen to the radio stream while running other programs. (Free)

Zillow Real Estate: The perfect companion for those lazy Sunday walks around the neighborhood, as you fantasize about which houses you might someday be able to afford. (Free)

Peggle: The latest from Seattle's PopCap Games, this is the game-of-the-moment in my household, supplanting Bejeweled and Bix, at least for the time being. Normally $4.99, it appears to be on sale this weekend for 99 cents. Dang, I should have waited to buy it.
