The Palm Centro is one of those dying cell phones that still has a large development arena on. There are many such applications that deserve special mention and many that I use everyday. All of these applications are completely free and no-frills attached!

Here are a few that I use everyday – these are the best Palm Centro applications:

Facebook for Palm Centro

This free offering from Palm inc. makes using Facebook a breeze. The social network’s premier software on the Palm Centro is complete with status updating and wall-posting services, meaning whenever you have GPRS or EDGE services activated on your Palm Centro Smartphone, you can use Facebook for Palm Centro to access your entire friend-list on the go, update your status, look at other people’s status and even post on your friends’ walls! Also included is personal messaging, and commenting on photos too!

This version also includes uploading pictures straight from your Pics & Videos application on the Palm – no more MMS-ing the pictures! Just select the album, and the program will optimise the picture for uploading!

Plucker Centro App

Plucker is an palm eBook reader that is open source and completely free. It also doubles up as an HTML reader for offline websites, complete with pictures and formatting. The images can be clicked, panned and zoomed into, while the fonts can be changed and sizes can be manipulated.

This software is so feature-rich that there is no scope for explaining everything here – and it is hard to believe that it’s a completely free app! But it is one of the best Palm Centro applications. Project Gutenberg, the free eBook site offers downloads exclusively on the Plucker form for Palm OS cell phones.
