I have a Verizon 4s, and have an unlimited plan and am no longer in my 2 year agreement. Because I'm unlimited is why I haven't upgraded yet well I've been having wifi problems the last few days and then last night I rebooted and now I can't turn wifi on at all. My wife's 2 years is up at the end of the year and we were waiting until then to possible leave verizon and go to t-mobile for better plans (she's not unlimited) I can't afford an unsubsidized purchase right now because we are paying down debt plus it seems kind of pointless to buy a new one now if might leave soon anyways. I might just suffer with 3G data or pay the deductible for a replacement (1 year is up)which also seems like a waste of money. My question is how long would you go without wifi to avoid paying for a replacement, and what would be the worst time in upgrade cycle for you to still have to get a new phone instead of waiting it out for the next version.
