Itching for a new Sprint handset, but your upgrade date is still a ways off? You might be in luck, as a newly-leaked Sprint document has shown that the carrier is offering some customers an early upgrade. According to the doc sent to SprintFeed, there's a silent promotion running now through December 31st that'll allow some Premier customers to upgrade early to any CDMA handset in the Now Network's lineup, including the iPhone. The deal is said to be only available at corporate-owned stores, and before earning the upgrade you'll need to have your account reviewed by a sales representative for specific promo codes.
Sounds like a pretty good deal to me, especially considering that Sprint Premier is going the way of the dinosaur and most of the benefits of program are ending once the year is up. If you'd like to see if you're eligible for an early upgrade, mosey on down to your local (corporate!) Sprint store and ask your friendly rep to look into the promo. Just don't forget to come back and let us know how it went when you're done, k?
