Best Buy has begun advertising their comprehensive iPhone 4S pre-ordering program which includes black and white iPhone 4S model in 16/32/64 GB flavors and with service agreements from Verizon Wireless, AT&T and Sprint (carrier plan breakdowns here). You can pre-order the handset over at the Best Buy site today. Expect deliveries to be made next Friday, October 14. The retailer is sweetening the deal with the Phone Trade-in program allowing you to sell Best Buy your used device in good condition and claim up to a $300 gift card, which can be redeemed against an iPhone 4S purchase as well.
The iPhone 4S is also offered for pre-order via the online Apple store, in addition to the Verizon Wireless, Sprint and AT&T online and brick-and-mortar stores. AT&T’s online pre-ordering system experienced some hiccups this morning, but those issues appear to have been sorted out at post time. Apple, too, will buy your used iPhone 4 for up to $200 and you can fetch some really attractive prices over at eBay and Gazelle. Other popular choices include Craigslist, NextWorth and SellYourMac.com.
If you’re in the market for an iPhone, you might also find this AT&T pricing grid handy, included right after the break.
