AT&T’s done it flattering clear how this ascent sitch is starting to go down for existing customers moving to an iPhone 4 on a 24th of a month, though if you want to double-check and make certain you’re great to go (we can’t censure you), there’s an easy approach that was briefly mentioned yesterday: dial *639# upon your current phone. You’ll be returned a content message from AT&T detailing your incident — possibly you’ll be told you can get the full ascent cost (meaning $199 / $299 for a 16GB as well as 32GB, respectively) or you’ll be eligible during some sold date in the destiny. Not all’s lost in the latter case — you can still compensate $200 more for a phone as an “early ascent,” that is less than the no-commitment cost of $599 / $699. We’ll have the some-more extensive relapse in our full iPhone 4 beam entrance later currently, so stay tuned!
