I ask because me wife is away for a month and this would be the ideal time for me to try to score one on ebay (just saw one go for $312 a few minutes ago so they are coming into my target zone). thing is I would be using my regular sprint phone for at least a month and thus would really only use it at home with my wireless or in a starbucks or something in the meantime...so would that work or does the phone have to have a sim card to work. also would I be able to get the 1.2 update via wireless or do you need to do that through the spring network or something. sorry for the dumb questions but I have never owned a smart phone before...thanks...
