I’ve been using Skype over 3G ever since it came out (first with VoIPover3G, now with 3G Unrestrictor) and I have to say that quality sucks. I get dropped calls, sound dropping in and out, weird noises during the call, etc."
We have the largest and fastest 3G network in the world here in Australia (44mbps downlink in the cities, 21mbps everywhere else – 99% of the population have 3G), and being a fairly small population – congestion isn’t an issue. VOIP over 3G works, but it totally sux. Like really, unless you can’t afford to make a phone call (unlikely if you have an iPhone) then it’s not worth the mucking about.
Cellular data connections are very bursty with high amounts of latency. Fine for browsing the web, or streaming media where the player has a buffer, but pretty awful for having a real-time duplex conversation. Which is why I really am ok with just using Skype over wifi.
A few people post quotes to the effect "quality is so-so but it's good enough for me," but most responses seem pretty negative towards the call quality.
