hi all, three weeks ago i bought an iphone (8g). Nevertheless i didn't activate it (with o2 in Uk) because threre are a couple of months to go with my Vodaphone contract. lately i follow the news for the new 3G iphone. i am thinking to do the following thing: given that i don't need my iphone as a phone for the time being, i want to turn it to an Ipod Touch. How can i do that ? If later i am not satisfied with the 3G iphone, could i turn back to an iphone ? can you advise my for any web page or application that does this thing ? please note that the only thing that i can do by using my macbook is to browse internet, use iwork and itunes. nothing more nothing else. i have also a pay-as-you-go sim card with orange. in case i have turned to an Ipod Touch, by putting at orange simcard can i use it as a pay-as-you-go phone ? and something else. assuming that i'm in london downtown (around City, or Mayfair), are there any free wifi services that i can use ?
