Does anyone use the portable hotspot as their main internet provider at home? I currently have the usual hispeed cable internet at my house and Im thinking I can save quite a bit of money by just using the free quick settings app and then use the optimus s as my "hotspot". I have an unlimited data plan but I fear that the amount of web use from my laptop usage may raise a few red flags when my data usage on my cell plan skyrockets. Any input at all would be great. TIA
