AT&T has announced new international data plans for iPhone users who are looking for a more affordable alternative than data roaming (other than swapping out for a local carrier's SIM).
* $24.99 iPhone International Data Package gives you 20MB of usage within 29 countries
* $59.99 iPhone International Data Package gives you 50MB of usage within 29 countries
The 29 countries mentioned include Australia, Austria, Belgium, Canada, China, Czech Republic, Denmark, Egypt, France, Germany, Great Britain, Greece, Hong Kong, Hungary, India, Ireland, Italy, Japan, Mexico, Netherlands, New Zealand, Poland, Portugal, Romania, Singapore, Spain, Sweden, Switzerland, and Taiwan.
AT&T cryptically mentions that "iTunes Radio" can use up data quickly (1 MB/minute) as one of its reasons for offering the service. However, "iTunes Radio" currently does not exist on the iPhone, leaving questions as to what was meant by the reference.
Update: AT&T has updated their site and removed the reference to iTunes Radio.
