Also remember it uses threaded text messages. When you go to your texts, it'll have the contacts and/or numbers you have been messaging w/. If you open up any of the contacts from there, it'll have all the texts you have exchanged. You can, of course, clear them if you choose.
Also, you can choose whatever text alert you want. You can use the stock or DL one through one of many apps. There's also the tried and true ways of the past, like phonezoo or zedge (which also has an app, now). Personally, nothing is more appropriate than hearing your phone's robotic voice belch "DROID!"
