We let you know a couple days ago there were a few apps that had already been updated via the App Store to support iOS4. Since then we’ve seen a few more roll out.  Some developers have really taken advantage of the new APIs in iOS4.  Others seem to just be adding compatibility at this point.  Let’s hope a lot of them are working on substantial updates.  Hit the jump for some more iOS4 compatible apps!


Evernote (version 3.3.5) is one of the first I’ve seen to implement quite a few 4.0 APIs.  Not only does it come complete with fast app switching integration, but your notes will also be able to sync in the background.  This will be extremely useful for users who like to upload pictures.  I’m always doing this when I’m comparing prices.  I’ll take pictures of SKUs from different stores and tag them accordingly which allows me to flip through later and compare which ones are cheaper and which ones have rebates attached, etc.  Much easier than writing a note with all that information.  The down side to that has always been pictures take a bit to sync with the Evernote servers at times and keeping the app open the entire time was somewhat of a pain. Thanks Evernote! (Read more about Evernote and iOS4 here.) [iTunes link]


For now, it looks like LinkedIn has added support for fast app switching, but I don’t see much more than that at this point.  I’d love to see the LinkedIn app get a lot more intuitive than it is.  Hopefully they’ll be adding more support in future updates.  If you caught anything I didn’t on this one, let us know in the comments!

Windows Messenger

Not only is this one new to the App Store, it came out of the gate with iOS4 integration built-in.  It also supports alerts for Hotmail as well, so you’ll get notifications in-app when you receive new e-mails via your Hotmail account.  And again, if you see anything worth noting, let us know!

I know a lot of you have been waiting for this one. This update just hit the app store a few short hours ago. Pandora background streaming was demonstrated at WWDC 2010 and lots of users were excited to be able to allow Pandora to finally run in the background. This feature has been available for other mobile platforms for quite a while. [iTunes link]


Loopt is another company that's taken advantage of additional APIs available behind iOS4. Fast app switching, PNS alerts, and grid based navigation are a few of the features the new version of Loopt offers. [iTunes link]


One of the most popular blogging engines on the planet comes out on release iOS release day claiming Retina Display support? Even if they're just scaling text and UI elements, good on them. [iTunes link]
