Vodafone Italy 4G will work ONLY with iOS 6.1 update
Soooooo, after driving myself crazy with Vodafone italy and their 4G network, i finally have answers that i'd like to share.
1) you must "activate" 4G service, either online (through "190y" on their site) or directly from them (the store, or what i did, they have a live chat feature on their site).
2) you have to wait to receive a text msg saying it has been activated.
3) wait until iOS 6.1 is released (end of the month).
I have a factory unlocked iPhone 5 that i bought in italy and have traveled to the states with recently. as soon as i landed i had 4G service, without any modifications or updates or doing anything. i told voda all of this, and after 3 days, i got some answers. after doing some research, basically the new update with allow the 5 to use vodafones frequency.
bam. there you have it. no 4G until the update. oh, and you have to pay 10 euro a month extra for it.
thanks vodafone :-/
