Comparison of Free Twitter Apps in iPhone

I have iPhone 3G which is running on iOS 4.2.1. Since it has a slow processor and low memory, some apps crash all the time. Official Twitter app, “Twitter for iPhone” drove me crazy last weekend. So I decided to switch to a new app.

I tested some of popular apps in App Store with my own criteria. I also re-installed official app and tested it too.

Please note: The tests are not finished yet. Since I do not have an iPhone anymore, I will not be able to finish these tests.
