hey guys my names Dakota. I have had the evo 4g and my charger port broke so the store gave me a nexus s instead since the evo was on back order. I have a few question's. how can I make my battery last longer. I have juice defender but the battery doesn't seem to last any longer than my evo did. which was just barely acceptable. also I noticed the stock txt message app won't let you send more than 160 characters. I downloaded an other app and anymore than one page and it was gibberish. I finally found an app that? works great and doesn't do all of that. but was curious as to why it does it in the first place. also if anyone wants to give me insight on neat apps and different things and apps that work well with this phone I would appreciate it. thanks all I'm glad to be there.

So I've noticed when typing on forums if I go to correct or delete something I can't. It is usually once I've typed several lines. It won't highlight or take my curser where I want it. Why does anyone know? I went back to stock browser and keyboard and no change.its very annoying and once it does it I can't gobback to the end of my post and keep typing the cursor won't go there.
