Hello, I have had my Captivate for quite sometime. The thing I am always nervous to do is tether to my laptop, because I am afraid AT&T will spring a charge on me. So I had 2 questions. Can I tether with a 3rd party app that I buy from the market with no additional fee? ( easy tetherpro ) or can I even use the Samsung Kies option for tether ( I have one of the earlier versions seeing as I never updated it ) Or with using one of these entitle me to pay an extra fee? I was really interested in this because I have so much date left over. Thanks In Advance
