Also The phone tends to use data even if you are not using it. I have the same exact phone, and a couple of night ago i tested to see how much data consumes over night (9 hour period). i came up with almost 2.00 worth of data. Doesn't seem a lot but it build up.
I personally think you should get the 2gb it is a whole lot of data. enough for the whole month. And with little chance of you going over. But if you get the 200mb the second you go over in data you will be automatically charged another $15.
And one of the greatest things is that with 2gb of wifi you can use instand messaging apps such as AIM to send free text messages over the internet. It's totally free sending/receiving. And people could only send you messages if you are online. And if you had the 200mb you only have a minimal amount of time to use it even though you use a wifi.
If you use wifi your only safe at the places that have wifi but people don't stay in one spot all the time. So chances are you won't have free internet all the time. I'm not trying to convince you to get a 2gb i'm just saying that it's a good idea to get one and look at the benefits that come with it.
^^ That is not necessary, you can always turn mobile data off when not needed. There's also an HTC sense widget that you can place on your home screen to toggle it off and on.
If the OP doesn't think he'll use that much data, there's really no need for the 2GB plan.
Me on the other hand, I'm already up to 7GBs with 5 days left on my billing cycle, but that's because I tether and stream a lot.
