I have been using handcent since my first android which was at least two years ago. I am a big fan. Everything works well, online backup, good support, and they listen to their users and actually fix problems.
I have both.
Go Launcher EX - GO Sms.
Any other launcher - Handcent.
Go Sms is better IMO simply there are more customization features then Handcent. Go Sms widgets can be themed. Go Sms has several types of widgets vs Handcent's one widget.
Go Sms has sending animations while Handcent is just a pop. There are more themes readily available for Go Sms although cannot be utilized any other launcher.
Go Sms just has alot more going on then it's competitors.
Go Sms > Handcent, Chomp Sms.
Does anyone know, is there an app, or setting in an app that when you receive a message, and your phone is asleep, there's a popup but the lockscreen does not come on. It only shows the popup. I am currently using Handscent, but I am willing to change if anyone knows of one. Thanks
