Lost my iPhone 6 in the river over the weekend. I need a phone for work so I went to Apple store to get a replacement. Since I was in an AT&T contract, a new 6+ will cost $849. That's a lot to spend knowing a new phone is releasing in a month. Any good options for buying a phone now and upgrading after the S release? Trying to minimize the expense as much as possible but I need a phone ASAP.
