In my “research” over the last week, I’ve found a couple new iPhone apps that really caught my eye. Go forth and download!

Line2: In an effort to compete with and improve upon Google Voice, Line2 adds a second line to your phone, making it easier to separate personal and business call. Google Voice allows calls to be routed to multiple phones, but leaves the deciding of whether it’s business or personal up to the receiver. This particular app is also compatible with Android phones but is fairly pricey ($0.99 for a 30 day trial, then $14.95 per month after that). Click here to read more and watch the video tutorial.

Digg: The much anticipated app for Digg (social news website that allows users to submit, or “Digg”, any piece of content on the Web and then the most “Dugg” pieces appear on the front page of the site) was unveiled yesterday in the UK. Until now, there has been no native app for Digg, but only an iPhone optimized mobile site. The exact US release date is not known yet, but here is an inside peek at what the interface will look like:

Fisher Price Apps: Fisher Price has released three new apps aimed specifically at 2-4 year olds. They are “Chatter Telephone”, “See n’ Say”, and “Little People Farm”. Personally, I’m not sold on the idea of toddlers toting iPhones, but I suppose there are some instances that would require a child to be occupied by an app for 10 minutes or so (see: doctor’s office waiting room).

So, there you have it: the latest, greatest iPhone apps (for this week, at least). Enjoy!
