Review: T-Mobile myTouch 4G
The myTouch 4G comes with HTC's Friend Stream software. Friend Stream channels all your Twitter and Facebook account status updates into one place. You can post your own status updates, as well as filter through those of your social network friends. It will also link to Flickr. Friend Stream is an OK application, though I find that it doesn't refresh as often or consistently as I'd like.
What's missing? The actual, native Facebook, Twitter, Foursquare and MySpace apps. None of them are pre-installed. In fact, not even HTC's Peep Twitter app is pre-installed. Friend Stream is all you get out of the box. You have to go digging into the Android Market to find the official Facebook and Twitter apps. Why do that? It's annoying. I can't imagine that anyone enjoys interacting with Friend Stream more than the native Facebook application for Android.
Android supports pretty much any and all social networks. The Android Market is chock full of apps that interface with them. Leaving them out of the initial build of a phone's software just makes extra work for the end user. Tsk, tsk, T-Mobile and HTC.
