how many megabytes do you have on your plan? Cause I use BBM, Viigo (an RSS feed reader) and I browse the internet. I have the unlimited BIS, so I don't really count.
I am hearing, but I have the curve myself. I've read some places that certain models of blackberrys don't work with certain models of HAs. It doesn't seem to be that much of a problem though.
I don't really use my phone to call much. The Curve is great for texting/e-mails/messaging, etc...
