I am thinking of buying a tivo to replace my old replaytv. The R54080 is on sale at Buy-dot-com. However, I once bought a tivo in the past, only to find out that it could not be setup without a land-line phone (which I don't have). I do have an in-home wireless network, and can easily buy any adapters I may need. There are lots of posts about determining whether you can do this by looking at the serial number on the unit, but I'd rather avoid purchasing it altogether if it can't be set up without a landline. So: Does anyone know if the Tivo R54080 Series2 has the software needed to be setup and used without ever having a land-line phone connection? Thanks in advance for any help!
