Admittedly I've not seen the 'release' or statements such as this.
Also the CDMA / GSM difference is a problem. The US has remained behind the times with CDMA / TDMA technology and pays the price for higher costs of additional development for additional technologies, which conveniently for Verizon keeps customers on their network.
- I see your new response - I agree, here it's not easy. T-Mobile appear to have a good setup. a reduced plan cost for hardware owners... That is 'new' here, but in the UK if you have no 'contract' or bring own hardware I think ALL companies offer simple moves between networks. They are ALL GSM... Simple
