As claimed on 9to5mac, Apple could be preparing for a major iPhone upgrade promotion event, starting on May 8.
Apple will be contacting upgrade-elgible iPhone users with older iPhone models via email to come into their local Apple Store to update to a new iPhone 5s or iPhone 5c.
This upgrade is rumored to be coming just to boost up iPhone sales at Apple Retail Stores.
It is worth following this rumor, as both iPhone 5S and iPhone 5C are top products and we are really interested in seeing what Apple could offer people to choose an upgrade.
Anyone received an upgrade offer letter or e-mail from Apple lately?
