Sprint says the iPhone 4S, 4 add up to its best 'device family' launch ever (Update: AT&T too)

After ignoring and teasing the iPhone, Sprint has its own Apple handsets to sell and apparently its customers have responded to the iPhone 4 and 4S. A press release just went out calling this Sprint's "best ever day of sales in retail, web and telesales for a device family" -- hopefully they double checked the numbers this time -- in the company's history, as of 1PM ET. Predictably, Sprint's unlimited data pricing compared to other carriers is being credited for the (unspecified) new high water mark in sales. Check the release itself after the break for the rest of the victory lap, but we'll wait for actual numbers before deciding on the big winner of today's launch.

Update: AT&T just couldn't let Sprint hog the moment, sending out its own missive claiming the company "activated a record number of iPhones on our network - and is on-track to double our previous record for activations on a single day". It's included after the break, and of course we'll let you know when / if Verizon fires a few shots off in celebration.
