As the world awaits Apple's announcement on Tuesday, some people are ditching their old iPhones early in anticipation.
"So the frenzy building towards the iPhone 6 launch is starting to happen," said eBay Vice President of Verticals Jeff Somers.
Somers says eBay has seen a 30 percent increase in old iPhone sales in the past week. The average sales for a iPhone 5s 32 GB is about $493.
"You have customers on the older versions of the phones, iPhone 4 and iPhone 4S, who are looking to trade up to fives," Somers said.
eBay is so confident you'll be able to sell your old device, they guarantee it.
"If you list your phone on eBay and take our pricing guidance and you try to sell your phone on eBay, if for some reason that phone doesn't sell, we'll give you a $100 gift certificate," Somers said.
Palo Alto based Glyde facilitates the sale of cell phones between the seller and buyer. The company has received three times the amount of visitors to its website, than the last iPhone announcement.

California company ecoATM allows you to trade in your phone at a kiosk and receive cash on site. Exchanges are soaring in San Jose, but the big rush is expected later.
"The uptick happens not on the iPhone announcement but it's generally when they start shipping two, three, or four weeks after the announcement," ecoATM co-founder Mark Bowles said.
All the companies say consumers should trade-in now before it's too late.
"As we approach launch, prices will start to come down as more folks are trading in and selling their phones," Somers said.
Sales numbers, that may point to the most anticipated iPhone ever.
