I did "iwlist scanning" earlier and noted several other networks. However
they're all on channels 6 and 11 so I thought I was safe with channel 3. The
other networks are 54Mb/s networks, does that affect things? And 22Mhz
bandwidth, does that mean 11Mhz on either side so at least 5 channels
separation? So only channels 1, 6, and 11 are actually useful?

I specifically bought a 900Mhz phone instead and have been suffering with poor
sound quality. I hope it's worth it in the end :)

I wonder what else could be causing interference though. The router's case is
off, can the motherboard or other cards cause interference?
