said by iansltx:If your phone is UMA compatible (some, though not all, T-Mo phones are) you can do this...and it works on ANY WiFi hotspot, which is pretty cool.
Also means that you can get away with a $50 wireless router rather than a $150 femtocell. Though OTOH most phones won't work with the tech.
The problem with that is incoming calls. 3g reception inside my building sucks (although edge works perfectly fine). The point of this femtocell is to provide full 3g signal bars for both incoming and outgoing calls (no more missed calls at home). You can make a phone call through voip, but you can't receive calls if there's no 3g/2g reception. Femtocell is their solution.
