I'm new to AF, but I've been lurking here for about 2 months. Did my homework and ended up buying the Samsung Moment and Samsung Exclaim for my girlfriend and I with a new Sprint contract. We're both thoroughly pleased with our phones and our plan. But I do have a question that I haven't seen addressed here. I jumped through all the hoops and was finally able to install PdaNet 2.17 on both my computer and phone. I tested it a little after getting it connected and was pretty well pleased with the performance of both the phone and the software. However, I will not be tethering my phone again until I can find out whether or not Sprint will bill me for it. As far as what I can tell from online sources the data plan truly is unlimited and Sprint cannot tell for a fact if my phone is tethered or not, although the bandwidth usage will be significantly higher during tethering sessions. BUT, a friend of mine informed me that Sprint knows when you're tethering and will charge you as if it is a separate line or however they can. All I heard was that it would cost me. I'm sorry for the long post, but I included the details for clarity's sake and as an insight into the kind of posts the AF community can expect from it's friendly neighborhood HampMan. Any input to the subject matter will be greatly appreciated and I thank you all in advance.
