Hello, First I did do a search and not a ton of information on the slingbox and using the new iPhone 4, so I figured I'd start a new thread, sorry if this rubs people the wrong way.... anyways on to my questions. I'm interested in picking up a slingbox & downloading the slingbox app for my phone. Now am I correct in saying the difference in the Slingbox Solo & Pro HD is that the pro HD allows for multiple inputs while the solo only has one? I only want to hook it up to my Comcast Motorola HD DVR so i'm assuming the solo is good for what i need it for. I plan on hooking it up wired to my Airport Extreme, any issues there? How is it over 3g on the iphone 4? Amazon has it on sale for $150 + $30 app = $180 for live tv & dvr access? Pretty good IMO Need some feedback on this subject and how people are liking it / regretting it? Thanks for all the comments and hope you can help me sort things out!
