About a no commitment iPhone 4...
If you bought an iPhone 4 without commitment could you still use Skype with just WiFi? I suppose you wouldn't be able to use the GSM service for VoIP unless you signed up with AT&T. So, don't they have a "Pay As You Go" plan for iPhone 4? Also, what about buying an iPhone 4 from say the Australian store when it's available over there? I think they might sell iPhones unlocked. Basically I'm trying to find out a way around AT&T while still being able to use the GSM service so I can eliminate monthly telephone bills. I have no problem paying for Skype calls as they are much more reasonable.
There isn't a pay go iPhone 4. People who have prepaid iPhones are either using a pay go SIM from a 3 year old iPhone 2G or using another type of AT&T prepaid SIM with an unlimited data package on it.
I'm using a pay go prepaid 2G iPhone SIM in a 3GS and I want to buy a no commitment iPhone 4 and cut down my SIM.
