With 4G LTE Android phones rolling out this week from AT&T, namely the Samsung Galaxy S II Skyrocket and the HTC Vivid, customers looking to upgrade will find that they suddenly have access to blazingly fast data speeds on their mobile devices. But how can small biz, with limited resources and budgets, truly leverage the latest Android tech? Today I’m going to take a look at 3 Android apps that will change the way you organize your data and stay sane while on-the-go.

1. Evernote

If your organization hasn’t already standardized on Evernote for taking and sharing notes, now is the time to start. If you’ve never heard of Evernote before, then the best way to describe it is that it works like a digital backup of your brain. You can input notes, record your voice, take pictures, clip webpages, and more straight into Evernote. The Android app seamlessly syncs to your desktop computer and tablet, making all of your materials available wherever you are. Whether you’re sharing meeting notes, recording a conversation with a client, or simply taking a picture of something you wanted to remember to take a look at later, Evernote is an invaluable tool for recording and easily referencing and sharing information no matter what the format. But the best feature for small biz is how easy it easy for team members to share their notes with each other. I’m even writing this blog post in Evernote so I can it on my iPad later. Premium plans are as low as $5/month or $45/year, so there’s little reason not to take your organization’s organization to the next level.

2. Dropbox

If you’re not storing files in the cloud, then you haven’t actually gone mobile yet. Not only can you access the same files on your desktop and your smartphone (no more emailing yourself files when you need them!) but you can easily share them with coworkers as well. Dropbox has been in the game for a long time, so they’re easy to recommend. Plus, if you’re picking up the HTC Vivid this month, the choice might be easy—you get 5GB of free storage on Dropbox simply for being an HTC customer.

Users on other phones, however, will find that they have a lot of options to evaluate, from Mozy to Box.net, and SugarSync to platform specific options like Apple’s iCloudMicrosoft’s SkyDrive and Ubuntu’s One. Because they all make sharing and collaborating on files easier, and allow you different ways to access your data while on the go, they’re all great solutions to make the most of your new Android phone. The important thing for your organization is to evaluate each and figure out what price you can afford, the amount of storage you need, and how well it integrates with the laptops, smartphones, and tablets you’re already using. Oh and remember, always encrypt important data before you upload to the cloud!

3. TripIt

If I could have one app, it’d be one that got me more legroom on flights. Failing that, TripIt is the next best thing. By organizing all of my travel, rental cars and hotel bookings in one convenient app, I never have dig through my email or print confirmations. I simply make sure to email TripIt a copy of my info when I book a flight, hotel or car, and TripIt automatically tracks and helps me share all of my travel details. Whether you need to alert your family or your boss about an upcoming flight, TripIt makes it dead simple to share your trip’s details.  It even adds everything to my calendar for me. We talk a lot about going paperless, but we’re only ever motivated to do it when the electronic solution is actually easier. TripIt is that killer app that actually makes travel easier because it’s the all-in-one resource for the travel details you’ve always struggled to track on your own.

But don’t let me tell you what to think, what about you?  Are you using any of these apps? Are there better alternatives? What are your “desert island” apps you can’t live without?
