Let the hive mind of Engadget get that for you.
"As someone who doesn't reside in the USA, I was wondering what would be the best way to get internet for my computer in the US for a couple of weeks? If it were Europe I know I'd look for some prepaid data. Is there anything similar offered by American carriers? A MiFi or a data SIM that I can tether from would work, but I'm trying to maintain a tight budget. Help!"
Not sure if the WiFi store is going to work on EDGE but yes EDGE is slow, so I will not feel really bad if it works only on WiFi so at least you have a better expectation that you will be able to download your purchase right away.
The next interesting thing : so we know for sure that there is a software update coming for the iPhone later on this month to add the iTunes WiFi store, but what else are they planning to add ?
