Although I've read about a few people saying they use Handcent SMS for their messaging app, I've just been using my default messaging app for 2 reasons: 1) I didn't like the "bubbles" that I've associated Handcent SMS with, and 2) I liked the default messaging app just fine. WELL... I read that Handcent SMS has a setting that will push a pop-up that will wake your screen and show a little window for an adjustable amount of time- so you have a visual alert that you got a text, so I decided to check it out.. This app is the SHEET!!! There are TONS of very useful settings/ customizations that you can do for your texting pleasure/ convenience! I HIGHLY recommend it. Some of the things that I really like: 1) I LOVE the pop-up. (you can adjust the time that it stays popped up, dim or bright, detailed or private, and 3 different versions of options that also show on the pop-up, that also offers a quick reply) Very handy. 2) You will also have more optons regarding the notification that shows up at the top of your phone. 3) You can set up a missed text reminder, and adjust the alert timeframe. 4) You can choose ALL of the colors (theme, send/ receive backgrounds, send/ receive text, etc..) 5) You can adjust if you like the normal messaging format, or if you prefer the bubbles.. 6) You can download a separate Font app, that lets you choose all different types of font to further "personalize". (I haven't tried this yet) 7) and really, SO much more options that I am not even mentioning here. My texts even seem to send faster! Oh, and when you are composing text, hit menu, and one of the options is to attach pics, sound, voice recordings, all kinds of attachments. THEN, I also downloaded Handcent Keyboard... The best part of this is that it brings back the T9 Predictive text keyboard that I miss so much from my Rumor. It is a virtual keyboard that is just like a normal phone keyboard. If you like the T9 predictive text input method, this app brings that back. It takes some getting used to, but I am so glad to have that sort of keyboard on my Moment now, and I have already gotten used to it! BIGGEST TIP: Google Handcent SMS, and read the FAQ, and other detail on the website. This will show you how to adjust your settings to turn off the default messaging and messaging notifications, and also how to switch from the Android keyboard to the Handcent keyboard in your settings. I really think that investing some time to thoroughly review that website will drastically help with your satisfaction of the SMS and keyboard apps. I really love the text pop-up, missed text reminders, and my old-school virtual keyboard that I've gotten back via these apps and I thought I'd share my experience with you guys. Hope it helps.
