Hey everyone. First time with a TRUE smartphone. I had a Samsung Jack for the last year and a half and just upgraded to the Captivate throught At&t. Just got it last night and so far it is amazing. I do have a few questions... First off, how do I keep my data usage down? I constantly worry that it is eating up my data plan. I really don't need a smartphone and I will mostly use it to check email with very minimal websurfing. I did download about 15 apps last night since I get $30 in free data with the upgrade. If I use check an email and then exit, does it still run in the background and eat up mb's? I did just get the 200MB plan for now because I really don't think I will use any more than that on a normal basis. I downloaded AppKiller and use it all the time... Next, if I open AppKiller, I see that the At&t Nav. is on there as if it is was opened for use, which it wasn't. Is it possible to disable it? I can see me using it once a year MAYBE. Other than that, what are some other tips on keeping it low? Thanks and I appreciate the help in advance.
