As you may or may not have noticed, “smart phones” such as the iPhone and the Palm Pre seem to be the one thing that’s on everybody’s mind these days. Talk of these little mobile wonders seem to permeate throughout all forms of mass media, from print to late night talk shows and beyond. Even highly respected blogs such as this one “believes the hype” from time to time. On today’s action packed episode of the Free Line, we will be taking a look at four tools that will attempt to bring of that “3G style” to your web browser … and vice versa.

iphonesender – For Firefox. This little tool does only one thing — sends a customized link from Google Maps to your iPhone — but it does it well. Sometimes the simplest applications are the best.

PinPoints – For Firefox. This handy little addition sends large amounts of map-based information to the mobile phone of your choice. While any modern phone will work, a working GPS module is needed if you want the “full experience.” Unlike the other add-ons mentioned here, PinPoints requires you to sign up for their service. Although the non-existent price tag isn’t a problem, the simple fact that you have to subscribe to yet another service might bother a few people.

iGtalk – For Firefox. Ever wish that you could use the iPhone Gtalk application without having to break out your phone? Now you can, thanks to iGtalk. When activated, a familiar, iPhone-like application appears prominently in the left hand corner of the browser. While it might seem a bit redundant to some (Gtalk is available for all three major OSes), this is a tool that many could find to be useful, especially if that person is already familiar with the mobile interface. All in all, iGtalk is a great way to bring a little bit of that iPhone magic to the desktop, even if its existence tends to defy all logic.

Zhiing – For Firefox. On the surface, Zhiing appears to be yet another add-on designed to get maps from your browser to your iPhone. Look closer, however, and you will find an interesting little service lying underneath. Unlike the other services mentioned here, Zhiing does more than play digital taxi. It actually turns every street address into an interactive link. From there, you can choose from a variety of options, including getting driving directions and finding nearby attractions. Remember: Zhiing is still considered to be in the dreaded “beta stage.” Not everything is going to work the first time out (if at all). If you think that you can deal with these few minor inconveniences, however, it would be in your best interest to give Zhiing a try. You will be glad you did.
