Technology changes quickly these days. Just think, a few years ago, we all thought a flip-phone was revolutionary. Today, our mobile devices are much more advanced. Heck they’re practically handheld computers (the future is right around the corner). But there are so many choices out there–Blackerrys, iPhones, Google phones, and a slew of others. How do you compare and contrast? And more importantly, if you work in PR or communications, how do you find the smart phone that will best meet your personal and professional needs?

Introducing David Erickson, Lauren Fernandez and Jennifer Mitchell. Three PR pros who use their smart phones in their day-to-day professional lives. Each will examine the pros and cons of the phone they use, discuss helpful applications and talk about how they use the phone on a daily basis.

Review: Three features I dig:

Social media applications (Twitter, Facebook, Linkedin, WordPress). Hands down, the application store on the iPhone goes above and beyond any other. I am able to customize applications to my needs and information is updated in real time. I can handle multiple Twitter accounts, respond to blog comments and check our Facebook fan pages with ease. The Application Store also makes it easy to install programs from either my laptop or the phone. With social media constantly being integrated in our daily lives, it is important to have applications to best fit the needs of a PR professional.

E-mail. E-mail is probably the one thing that I believe the iPhone can improve on, and where my BlackBerry was actually better. PR professionals are constantly on the go and need to be able to receive and respond to emails in a sufficient manner. Unless you are able to constantly hit the refresh button, my iPhone email will only update itself every 15 minutes. When I had my BlackBerry, I received emails on the spot. I was also able to manage all of my email accounts from one place, where the iPhone makes you go from account to account. I have a friend who works for a technology magazine, and his advice to me was “If you are buying a phone solely for email purposes, go with BlackBerry. You need an iPhone for everything else.”

Sidenote: If you use Exchange, make sure to have IMAP enabled so that it will be compatible with the iPhone.

Web browsing. I like checking for clips and reading the New York Times from my iPhone. The Web browsing on my iPhone is much better than my Blackberry, and the speed at which my phone goes from browser to Web page is much quicker than the Blackberry. Also, the ability to touch the screen and zoom into a Web site makes reading much easier. The Blackberry Storm can do this as well, but I found it wasn’t as natural as the iPhone. Safari is also able to display complex Web sites easier.

One thing I love that was not mentioned above: The sleek design of the iPhone makes it easier for me to carry it around than my bulky BlackBerry.

Device: Blackberry Curve

Review: My Blackberry Curve is the best investment I’ve ever made for my business. I pay $120 a month which includes 2,000 shared minutes with my (non-chatty) boyfriend and unlimited data.

I purchased my Curve two months ago. I chose it over the Storm on the advice of a sage salesperson who suggested I needed a bit of patience for the Storm. Great advice. I wanted to use my phone now, now, now! My learning curve (pardon the pun) was zero.

Within thirty minutes my e-mail account, TwitterBerry and Facebook were live on my phone. (These are my do-or-die applications.) FYI- a Blackberry can handle up to five e-mail accounts.

My Blackberry does everything I need it to do for public relations purposes. I am always-on with my clients now, which gives me great piece of mind. Last weekend I replied to a reporter inquiry at 9:30 on a Friday evening. I can access Twitter 24/7 or get some social fun on with my Facebook friends. I am also able to view and edit documents. (This was a big selling point for me.)

My Blackberry’s Roxio media manager has become one of my favorite applications. I can hook in a USB port, boot it up and transfer photos/videos (any media) from my phone to my computer. This means that I can take pictures anywhere I am and utilize them on my blogs later. I find that I pay attention to my surroundings more often now and think: how could I use this later?

If you don’t have a navigation system on your phone, you’re missing out. I often have to navigate to new places in town for client meetings or networking events. My trusty Verizon Navigator came “traffic enhanced” on my Blackberry. I now know if I am going to run into a delay before I leave the house or while I am en route.

The Blackberry is not without its flaws. I find it amazingly annoying that there are character limitations on text messages. I’m sure my friends find it equally annoying when I sent “text blasts” when I have more than 160 characters worth of subject matter to share. And I’m not really sure why the default setting orders every e-mail I send (on my computer or phone) to go to myself on my computer AND phone. As the pack-rat I am, I can’t bring myself to change that setting. But it seems excessive, no?

All and all, my Blackberry reminds me of a miniature computer. It’s clearly not nearly as powerful but I’m always connected. For me, that means I’m always available for my clients and that’s the kind of service I aim to provide.
