ust when you thought it was over, the iPhone on Verizon rumor is back...this time with a claim the iPhone is coming to Verizon in January 2011. The fresh report comes courtesy of Bloomberg news, which cites two sources "familiar with the plans." This is odd timing for a new iPhone-Verizon rumor considering that Apple just announced the iPhone 4 had the most successful product launch in Apple's history, and Verizon just made a big deal over the upcoming launch of the Android-based Droid X. Why dampen customer enthusiasm for either device with a tired, old rumor that just refuses to die? That's just one of the many reasons, I'm wondering, yet again, how much truth there is to this reason. Here's another five things to consider before buying this rumor for the umpteenth time. Engadget recently dug up a court document where Apple appears to admit that it has a five-year exclusivity contract with AT&T for the iPhone expiring in 2012, not 2011. Yes, as has been noted before, AT&T's exclusivity contract could have been amended to shorten the deal in the wake of AT&T's well-publicized service issues.
